Hello, here I m providing you the details of the DRDO, Long Range Solid State Active Phased Array RADAR as under:

Long Range Solid State Active Phased Array RADAR
LSTAR system developed under the Technology Demonstration Programme is a Long Range, Multifunction Solid-State Active Phased Array Radar, mainly for surveillance, detection and tracking of airborne targets.
The Radar carries out target detection and provides measurements of range, azimuth, elevation and target speed. The Radar Data Processor (RDP) built into the system provides target identity, target state vector and maintenance of multiple target tracks based on updates.
The Radar operates with Low as well as Medium PRF waveforms using Pulse Doppler processing.
