Unlike the design of Strategic Radars, which detects point targets, the design of Atmospheric Radars is very complex. These Radars deal with distributed targets with minimal back scattering (RCS). A VHF Mesosphere Stratosphere Troposphere (MST) Radar, having very high power aperture product (Figure of Merit) was designed, developed, installed and commissioned indigenously for ISRO/DOS, which is being operated over last 30 years. Design/developmental details of this Radar will be discussed in the interactive lecture. Co-sponsored by: IEEE AP-MTTS SBC IIT Kharagpur Speaker(s): K. P.
