摘要:The external commercial broadcast illuminators are not designed for radar, and the illuminators of opportunity usually have Dopplervarying structures. These structures usually cause ambiguity sidelobes in Doppler dimension. To solve the ambiguity sidelobe problem, a method of mismatched filtering that deals with the ambiguity Doppler sidelobes is proposed. In this new algorithm, the mismatched filtering factor is acquired based on minimizing the signal energy loss and the total energy of the ambiguity Doppler sidelobes. The experimental result shows the effectiveness of the proposed algorithm.
