Radar “Malachite”

Interference-immune VHF radar with digital processing and automatic data transmission MALAKHIT radar is intended for:

– automatic detection, determination of the current coordinates (azimuth, range, course, speed and altitude in conjunction with the PRV) and parameters of the trajectory of movement;

– automatic transmission of data on tracked targets to the command post, as well as to consumers of radar information when used as part of RTV and ZRV radar reconnaissance units in conditions of intense images from the underlying surface and ground objects, the action of organized active, passive and combined interference;

– detection and tracking of targets with small RCS using stealth technology;

– detection and tracking of targets in the sea area.

The main directions of the development of the “Malakhit” radar included the introduction of: digital signal processing, primary and secondary processing of radar information, equipment for compensating for active noise interference, a digital tracking system for moving targets, automatic data transmission to distant information consumers, determining the radial speed of air targets, as well as the use of transistor transmitter.

The digital processing and display system is implemented on the basis of industrial computers and video monitors of automated workstations (AWP) and provides:

– detection and coding of the received echo signals with the formation of target marks and their display on the screen of a color monitor;
– selection of moving targets against the background of natural and organized passive interference;
– control of the radar operating modes;
– automatic control of radar performance and display of control results;
– simulation mode for training personnel;
– creation of target forms with the definition of azimuth, range, speed, altitude (when coupled with the PRV) and nationality (when coupled with the NRZ);
– formation and display of trajectories with the determination of the parameters of the movement of targets based on the received marks;
– automatic transmission to the automated command post of data on the trajectories of targets on each survey using the APD channel;
– interfacing with a radio altimeter of the PRV-16A type;
– interfacing with an interrogator of the “Password” or “Kremniy” type.
