In the application of radar dim target detection

dynamic programming (DP) is an effective method in integrating target energy.This paper analyzed the characters of images of dim radar multi-target with DP

and achieved multi-target detection by using extreme value theory.The probability of false alarm and the probability of detection have been analyzed theoretically.The results of the simulation show that the method brings 4~5dB gain of noncoherent integration compared with traditional detection method.
