Based on the analysis of the side peaks in passive radar using digital video broadcasting-terrestrial (DVB-T) signal, two methods for the side peaks interference suppression are presented: the side peaks identification (SPI) method and the side peaks elimination-intersection (SPE-I) method. The SPI method identifies the side peaks by their positions and amplitudes relative to the main peaks. The SPE-I method eliminates the intra-symbol side peaks and the inter-symbol side peaks by preprocessing the reference signal respectively, and obtains the main peaks from the intersection of the peak positions in the two cross-ambiguity function (CAF) diagrams. The SPI method can identify the side peaks without the power loss and may lose the main peaks masked by the side peaks. The SPE-I method can eliminate the side peaks and detect the main peaks masked by the side peaks at the expense of the power loss. Combination of the SPI method and the SPE-I method can overcome their disadvantages. The proposed methods can avoid the false alarms of the side peaks and improve the target detection performance.
