Abstract :
In this paper, we investigate the use of a new method for dealing with radar type signals. The adopted model is a sum of exponential sinusoids. The proposed method is based on a combination of a discounted recursive least square and phase differences approaches. This algorithm permits us to obtain a good performance of estimating the all parameters of the signal. Experimental results dealing with real radar cross section data are presented
