Abstract :
A new algorithm for multi-target angle tracking is presented using the antenna array output. It combines the discrete wavelet transform (DWT) based beamspace processing with MUSIC algorithm to track multiple target angles by recursively updating the center frequency of the spatial prefilter. Compared to the method of Lo and Li (1992), the improved performance of the proposed method is demonstrated by computer simulations.
