Many radars suffer from masking of weaker targets by stronger ones due to range sidelobes of pulse compression codes. A new method is proposed to prevent this by successively detecting targets and canceling their effects. Performance of the proposed method will be investigated in various scenarios with regard to existence of noise, targets, and the Doppler effect. Moreover, the performance of the method is compared with the other two methods known as MMSE and LS methods. I hope this book will be attractive for the ones who are interested in Radar Signal Processing.
