Real-Time Clutter PSD Computation Method for Pulse Doppler Radar

A range Doppler clutter power spectrum density (PSD) computation method for pulse Doppler radar is introduced in this paper.For the contradiction between precision and rapidity in clutter simulation,a novel and real time computation method is proposed for clutter PSD,with which the data of the area units are pre stored and then the clutter PSD is reconstructed at real time.High precision and high speed (The time of clutter PSD computation is less than 100ms.) are achieved by applying this method.
