Question

Problems 1. Find the received power P, expected from a radar and target having the following parameters: RF frequency=95 GHz (W band), transmitted power = 100 W, antenna beamwidth = 2º

in azimuth and 5º in elevation, system losses = 5 dB, target range = 3 km, target RCS = 20 m². Use Fig. 1.3 and assume operation near sea level to estimate atmospheric losses. What is the ratio in decibels of the received power to the transmitted power?
