Adaptation of the APES approach to DoA estimation problem in a rotating array radar

The problem of direction of arrival in a radar system that employs mechanical scanning to estimate angle is considered. The presence of clutter and noise with unknown spectral characteristics and the absence of training data, i.e. in-homogeneous evnronment, are assumed. The proposed approach is a variation of the APES (Amplitude and Phase EStimator) spectrum estimator that takes into account the motion and the response of the array. Computer simulations show high accuracy of the method.
