A radar system uses a threshold detection criterion. The probability of false alarm Pfa = 1010.

(a) What must be the average SNR at the input of a linear detector so that the probability of miss is Pm = 0.15? Assume large SNR approximation (see Problem 4.6).

(b) Write an expression for the pdf at the output of the envelope detector.
