SOV - SON-9 / SON-9A ("Fire Can" - strelecký rádiolokátor)

SON-9


A gunnery radar designed to track an airborne target, detect its coordinates in space, and guide the battery's anti-aircraft guns to the target (via the PUAZO's fire control station).


The SON-9 radar was developed in 1948-1950 under the direction of the designer M. N. Polozov (М. Н. Полозова s účasťou B. P. Roždestvensky, (В. П. Рождественского), K. I. Voroncova (К. И. Воронцова), B. N. Belugina (В. Н. Белугина) a ďalších.


The radar transmitted pulses generated by a magnetron with a dĺždĺž of 0.5 microseconds and a repetition rate of 1875 Hz. To ensure činactivity under interference conditions, it was equipped with four magnetrons with a frequency difference of 160 Mhz. In the transmitting system a centimetre heterodyne of the klystron type (resonator) was used.
The receiving system provided the processing of the received signals and their display on the range indicator and the circular horizon indicator and at the same time provided the processing of the data necessary for the antenna movement and automatic range measurement.
The antenna control system provided antenna movement in the mode of automatic full-circle or sector avoidance, manual pointing and automatic target tracking.
The radar enabled target designation from the surveillance radar and remote antenna control (aiming and bearing) from PUAZO (optical target tracking).
A certain shortcoming of the radar was its poor resistance to interference, which caused that when working in conditions of strong radio-electronic interference, the operator had to provide target tracking by optical means.
Military trials took place in 1950, where the characteristics were tested in practice and the device was accepted into the armament of ground troops.


SON-9A
In the early 1950s, in connection with the tumultuous development of means and forms of electronic jamming, the designers of the radar were faced with the task of modifying the radar for činnosť even under conditions of intense jamming. The modernized radar was designated SON-9A. Its design and basic characteristics have been retained, but an automatic re-tuning system has been added to the receiver circuit in case of detection of active noise interference (APS), ensuring automatic re-tuning of the magnetron and heterodyne to another working frequency, undisturbed by disturbances.
Military tests were conducted in 1955-1956 and confirmed the system's functionality and compliance with the specified characteristics. The modernized radar was accepted into armament and mass production was started.

Mobile shooting radar SON-9A (СОН-9А - Станция орудийной наводки) is, together with the paľby PUAZO-6 (ПУАЗО-6) (or the PUAZO-5 ([i: 2112758ccb])) control unit (or PUAZO-5 (ПУАЗО-5)) designed to control small- and medium-calibre anti-aircraft artillery. The radar can also work with the PUAZO-3 (ПУАЗО-3), or PUAZO-4 ()]ПУАЗО-4), but in these cases the LSPPM coordinate transformer (ЛСППМ) was used.


The SON-9A can track (avoid) airborne targets at a range of 55 km regardless of visibility and weather conditions, determine the coordinates of the target in space (azimuth, elevation, oblique distance) and provide them to the PUAZO and searchlight.
In addition to tracking targets whose coordinates are entered from the radar, it also allows to locate targets in automatic full-circle mode, automatic sector mode, and in manual overflight mode.


Used to control the fire of the following types of PL guns:
100 mm PLK KS 19 with PUAZO-6-19
85 mm PLK KS 12 with PUAZO-6-12
57 mm PLK S-60 with PUAZO-6-60


NATO codename: "FIRE CAN"
Operated on frequencies 2.7-2.9 GHz
Pulse rate fp=1249 imp/s
Accuracy of distance measurement: 20 m
Distance resolution: 125 m
Accuracy of azimuth measurement: 0.1°
Accuracy of position angle measurement: 0.1°


Introduced in the armament of more than 20 countries, besides the USSR, also in the USSR, Poľsku, GDR, Vietnam, ....
Licensed and produced in Poľsku.
Participated in several combat conflicts (Vietnam...)
