Revathi is operating in F-Band pulse Doppler radar used in the Indian Navy for air and sea surface surveillance. Revathi is a derivate of the licensed Polish TRS-19 radar (the export designation of NUR-15 «Odra»).
The mechanically rotating and hydraulically stabilized antenna uses digital beamforming. It simultaneously forms eight beams in reception (covering 50 deg in elevation) which are used for estimating height. The transmitter uses a traveling wave tube (TWT) as power amplifier.
