Radar complex intelligence and fire control 1L271 "Aistenok"

In order to successfully complete combat missions, artillery needs means of monitoring the results of firing, which make it possible to correct fire. In addition, an important task of artillery units is the suppression of enemy guns, which also leads to the need to use special technical means. Artillery units require special radar stations (radar), capable of tracking the flight of projectiles and determine the location of the enemy's guns or the point of falling ammunition. At the same time, such units are needed both by units armed with towed or self-propelled artillery, as well as with calculations of mortars.

Radar complex intelligence and fire control 1L271 "Aistenok"

In August 2008 of the year, during the exhibition MVSV-2008, the Tula NPO Strela (part of the Almaz-Antey Air Defense Concern) showed its new development for the first time: the 1L271 Aisthenok portable radar complex. This system is designed to equip units of the "company-battalion" level and is capable of performing tasks related to the detection of various objects, both on the ground and in the air. The main task of the 1Л271 complex is to ensure the operation of artillery units, namely, to determine the coordinates of the enemy’s artillery and to adjust its fire.

In view of the intended methods of application, the Aistenok complex was made in the form of a collapsible structure consisting of a set of modules and suitable for carrying a calculation or transport on various vehicles. The total weight of the system components is 135 kg. The assembly of the complex and preparation for work takes about 5 minutes. The 1L271 radar consists of a tripod with a turntable, a transceiver with an antenna, an electrical unit with a power unit, a unit for the primary processing of the collected information, a control panel and a radio station. The elements of the complex are connected using a set of cables.

The main objectives of the radar "Aistenok" is tracking the work of their own and enemy artillery. Thus, the complex is able to track in flight mortar ammunition of caliber from 81 to 120 mm. In this case, the automation calculates the parameters of a mine’s flight and determines its starting point or place of fall. In the first case, this information can be used to retaliate against the enemy’s mortar, in the second, to adjust the firing of friendly units.

Also, the 1Л271 system can be used to control the firing of artillery shells from 122 to 152 mm. In this mode, the radar detects the gaps of the fallen projectiles and calculates their location, so that the artillery can adjust its fire for a successful destruction of the target.

The third function of the 1Л271 radar is to detect tank-type ground moving targets. Information about the location of the enemy's equipment can also be transferred to artillery for striking.

The Aistenok complex uses an antenna made in the form of a two-surface mirror with orthogonal polarization and electronic switching in elevation and azimuth using an irradiating linear phased array. To simplify and simplify the design of the antenna is not equipped with mechanical drives for pointing. For this reason, the antenna is rotated in azimuth and elevation manually.

Information about the operating modes of the radar station, tags and trajectories of detected targets, security zones and other information is displayed on the color display of the control panel. To transmit information about the detected targets in the complex has a radio station.

Transceiver device radar "Aistenok" works in the centimeter range. Despite the absence of its own mechanisms of rotation, the antenna provides observation of the sector width 60 ° in azimuth. Target detection can be performed at a distance from 200 m to 20 km. The detection range of a particular target depends on its type.

The maximum detection range of 20 km is achieved in the case of ground targets of the "tank" type in the presence of radar visibility. In this case, detection is provided. tanksmoving at speeds from 2,5 to 60 km / h, with a probability of at least 0,8.

At half the distances (up to 10 km), the 1Л271 station can detect gaps in shells from 122 to 152 mm and can be used to adjust the fire. In this case, the gunners are able to compare the coordinates of the target with the coordinates of the explosive shells and make the necessary corrections.

When working with mortars, the maximum detection range is reduced to 5 km. At such distances, the Aistenok complex with a probability of at least 0,8 can detect ascending or descending flight segments of mortar mines and calculate the coordinates of the mortar. In addition, at the same distances, detection of mines of friendly artillery and the calculation of their fall place using trajectory data is ensured. The minimum range at which the 1Л271 system can detect an enemy mortar is 750 m.

The Aistenok 1L271 reconnaissance and fire control system intersects targets with an accuracy of several tens of meters. The values ​​of possible errors depend on the type of goal. Taking into account the error in topographic location in 3-5 m, the complex is able to calculate the location of the enemy’s mortar (if a mine is detected on the ascending flight segment) with an accuracy of 30 m. mines are calculated with an accuracy of 200 m. The error in detecting shells and moving ground objects does not exceed 30 m.

Radar "Aistenok" can be used at any time of the day and in all weather conditions that impede visual observation of the battlefield. The complex is powered by a gasoline electrical unit. The time of continuous operation of the system from an autonomous energy source is stated at the level of 6 h.

From 2008, the Aistenok Radar 1L271 is regularly shown at various exhibitions of weapons and military equipment. Nevertheless, data on the procurement of these systems for the Russian ground forces are not yet available. Curious newsassociated with the operation of the complex, appeared a few days ago. On January 15, the militia of the Donetsk People's Republic allowed the OSCE observers to their positions. During this visit, observers were shown various systems, including the Aistenok complex, used by the militia to detect shelling by the Ukrainian armed forces. Thus, the current conflict can be considered the first war in which a new Russian radar station was used.

Details of the supply radar 1Л271 in the NPT is unknown. Likewise, the plans of the Russian Ministry of Defense to purchase such systems in the interests of their own units remain secret. It cannot be ruled out that a new radar complex of reconnaissance and control in the course of the current conflict must first be tested and tested in a real war, after which its purchases will begin for the Russian armed forces.

        the complex is good, but it is clearly lacking in mobility. it would be ideal, it, like an American similar complex, put on an armored car. this will increase its protection against possible impacts of anti-radar missiles. and with a good reference to glonas, it is possible to realize the possibility of radar in motion. and the correct proposal was about the transmission of target designation in real time. it is important. but whether or not it is really not clear.

          In fact, everything is exactly the opposite. "Stork" is much more mobile. And much more versatile.

      Help "ZOO

      "Zoo" is certainly more powerful, the system is of a different level. I wonder how things are with the "Zoos" now. In the USSR, two radar complexes of the same purpose began to be developed simultaneously - 1L219 Zoo-1 (at the facilities of the Scientific Research Institute Strela) and 1L220 Zoo-2 (at the facilities of the NPK Iskra). Compared with the 1L219 Zoo-1 complex, the Zoo-2 Ukrainian complex is distinguished by its increased range.
      FSUE SRI Strela from Tula continued to modernize the Zoo-1 complex (in particular, work was done to improve the communication system and hardware and software for this complex). The new complex, developed by the enterprise, received the 1L219M index (modernized) and was first presented to media representatives in 2002.

        At the time of creation, it was even redundant. "Zoo" without artillery ACS makes no sense.

        It's a division level system, no less. And "Aistenok" - the battalion. At the same time, "stork" is more applicable in local wars, "Zoo" is purely a system of big war

            It's just that the same old "Zoo" worked out 40 trajectories per minute - detection, intersection, extrapolation.

            And "Zoo-1M" ​​is even more. It is impossible to process such information flows without AMS and, what is most important, it is impossible to use.

    It’s good for everyone, but it is also detected by enemy intelligence systems, so it seems to me that the range of 20 km is only for mortars, not enough, for 152 mm guns, I mean domestic

    I don’t know how things really are with the transfer of data from this complex, but I suspect that the data is displayed on the screen, then the person (operator) passes the information to another person (gunner) for further use.
    I do not think that it is sufficiently operational.
    Maybe I outplayed the battlefield laughing , but the ability to "mark" enemy equipment would be very useful both for artillery and tanks and for aviation. I do not speak for the infantry because such technical gadgets for the infantry are unlikely to appear in the near future. And even more so, because of the price, not everyone will be in service.

    I drew attention to the vidos of the Armed Forces of Ukraine, how the soldiers were shouting "Through holes" and clarified what was flying at them. In 20-30 seconds after the command it really flew in! I could not understand - are the listeners listening. In the course of NATO, the Ukrainians have already been supplied with similar equipment. I am glad that ours are catching up

    The Americans have supplied artillery radars to the Ukrainian Armed Forces. The militias also have it. True, the militias use it for counter-battery combat, judging by the results, and dill has mastered only as an "alarm" during shelling. Another illustration on the topic "nails with a microscope ..."

      As far as I remember, it was a question of delivering radar for notch mortar positions LCMR (500-10 000 meters), I doubt that there will be much benefit from such, given that D-30, MSTA-B, GRADY, self-propelled guns are used in all.
