PR-15 ground surveillance radar system

The PR-15 ground surveillance radar is man portable and provides long detection ranges for this radar type, transmitting low peak power. This solid-state, Pulse-Doppler radar, automatically detects moving targets out to 23 kilometers.
Fixed target cancellation, sub-clutter detection and inbound/outbound indication are achieved by range-Doppler processing using FFT. Low transmitting power, LPI capabilities and some ability of adaptation to radar environment are achieved by utilizing advanced pulse compression techniques including mismatching and waveform agility. Classification and target activity analysis are accomplished by using time-Doppler analysis combined with pattern recognition techniques.
The radar operates with high reliability, exposed to harsh field environment conditions, working according to an intensified profile of mission either day or night in any adverse weather conditions. PR-15 radar can be combined with an electro-optic (TV/IR) and Command and Control (C2) system to provide multi-sensor surveillance capability.

INSTALLATION

Radar can be rapidly deployed and be operated as:
Portable unit;
Stationary fixed based operation;
Mounted on a vehicle.

APPLICATION

The basic purposes of the PR-15 radar are:
Border protection;
Infrastructure protection;
Battlefield surveillance.

COMPOSITION

The system is comprised of three main units and some accessories. The main units are:
Transceiver (TR) and Antenna;
Radar Remote Control Display Unit (RCDU);
Tripod and Pedestal to support the TR and drive the Antenna, while scanning.

OPERATION

Two basic modes of operation are surveillance and perimeter protection accomplished by the next tasks:
Detecting mobile targets;
Acquiring their coordinates and velocity;
Target tracking;
Target classification.
