A certain radar has losses of 5 dB and a receiver noise figure of 10 dB. This radar has a detection coverage requirement that extends over 3/4 of a hemisphere and must complete it in 3 second. The base line target RCS is 6 dBsm and the minimum SNR is 15 dB. The radar detection range is less than 80 Km. What is the average power aperture product for this radar so that it can satisfy its mission?1.36. A radar has the following parameters: Peak power P = 50KW ; total losses L = 5dB; operating frequency fo = 5.6GHz; noise figure F = 10dB pulse width=10s; PRF f = 2KHz; antenna beamwidth 0 = 1 and Oel 5.

(a) What is the antenna gain?

(b) What is the effective aperture if the aperture efficiency is 60%?

(c) Given a 14 dB threshold detection, what is the detection range for a target whose RCS is = 1m?
