(a) Show how you can use the radar equation to determine the PRF f,, the pulse width 1, the peak power P,, the probability of false alarm Pfa, and the minimum detectable signal level Smin Assume the following specifications: operating frequency fo = 1.5MHz, operating bandwidth B = 1MHz, noise figure F 10dB, system losses L = 5dB, time of false alarm Tfa = 20 min, detection range R 12Km, probability of detection PD = 0.5 == (three pulses).

(b) If post-detection integration is assumed, determine the SNR.
