2.28. A monostatic radar has the following parameters: Transmit power 100Kw, transmit losses 2dB, operating Frequency 7GHz, PRF 2000Hz, pulse width 10 sec, antenna beamwidth 2 Az X 4 El, receive losses 3dB, and receiver noise figure 12dB. Assume that the radar uses pulses that employ 10MHz of linear frequency modulation and uses a processor that is matched to the transmitted pulse.

(a) What is the antenna gain?

(b) What is the effective aperture if the aperture efficiency is 50%?

(c) What is the effective radiated power of the radar, in dBm?

(d) Given a detection threshold of 13dB, what is the detection range for a target with a radar cross- section of 6dBsm?
