Arine is operating in the Ku-Band low probability of intercept (LPI) battlefield surveillance radar. It is dedicated to the detection of targets that include personnel, vehicles, and low-flying platforms such as helicopters, unmanned aerial vehicles, and ultralights. In the radar is installed licensed technology from the Racal Radar Defence Systems' MSTAR program.
Arine is a fully coherent radar. It uses intrapulse modulation and pulse compression with a compression ratio of 1:1; 20:1; or 200:1. The antenna features a parabolic reflector with an offset horn feed. The user selects linear or circular polarization depending on weather.
