In this problem, we consider target detection in a radar system. Upon observing a realization x of the random variable X which represents the return signal in noise, a decision has to be made as to whether the target is present or absent. The target amplitude is known and equal to A > 0. The observation is made in zero-mean Gaussian noise W (real-valued), whose variance is known and equal to o?. If the target is present (hypothesis H1), X = A + W. If the target is absent (hypothesis Ho), X = W. The likelihood ratio test for this problem is stated as follows: If Si(x)/ fo(x) > n decide in favor of H1: otherwise, decide in favor of Ho. If n 1, determine the probability of correct detection (target declared present when indeed present) and the probability of false alarm (target declared present when in fact absent). Express these probabilities in terms of the ratio a = Alo. If a = 4, which of the following represents the correct probabilities of false alarm and correct detection, respectively? Answers are rounded to the closest whole percentage value.
