Description

The Antenna Mechanical Vehicle consists of an antenna main frame, which houses the electronics and processors for the radar, along with coolant pipe assembly to dissipate the heat generated by the electronics.

The main frame was mounted on a a turn table using a slewing bearings, which enabled the antenna to rotate upto 330 degrees and tilt back upto 70 degrees. This gave the antenna an extremely wide detection range, enabling it to detect incoming missiles and also send a corresponding signal to Indian missiles to intercept the hostile missiles mid-air.

This system was developed in collaboration with the Israeli Aerospace Company (ELTA)
