Surface Movement and Perimeter protection Radar
The ELR 55303 is a Doppler radar with mechanical scanning of the antenna beam and pulse compression. Radar is designed for
- Detection of slow moving objects on the earth or sea surface;
- Detection of low-flying small-sized aircraft;
- Determination of target coordinates (azimuth and range), EPR, radial velocity and Doppler spectrum width;
- Selection and recognition of targets;
- Terrain mapping;
- Port Security.
