Design and description

edit

It is a 3D multi-beam and multi-mode fully coherent pulse Doppler search radar which functions in the S band (2-4 GHz). It can perform both surface and aerial search simultaneously. It is designed to support anti-air and surface-gunnery systems. The antenna in the Doppler sensor has a planar array for 3D multi-beam operations and a vertical array of strip radiators. It has programmable signal processing and is stabilized within a roll and pitch of 20 degrees. It comes in three variants - a larger dual-face version, a medium version and a small single-face version.[2][4]
