Abstract :
This paper deals with the Direction of Arrival (DOA) estimation for chi-square fluctuating targets. The joint Probability Density Function (PDF) of the amplitude in the sum channel and the monopulse ratio for a chi-square fluctuating targets presented in [1] is here used to derive several DOA estimators. The proposed estimators are obtained by following respectively the Maximum Likelihood criterion, the Method of Moments, and the Maximum Entropy Method. Their performance are characterized in terms of bias and standard deviation error.
