Question:

2.26. 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 t = 10s; PRF f = 2KHz; antenna beamwidth = 1 and 15.

(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?
