摘要：

In this paper the use of Digital Video Broadcasting. Terrestrial (DVB-T) signals as waveform of opportunity for Passive Bistatic Radar (PBR) is addressed. A new approach for DVB-T Cross-Ambiguity Function (CAF) evaluation is proposed, which exploits a linear filter based on the knowledge of the expected value of the ambiguity function. The proposed approach is able to remove the unwanted deterministic peaks in the CAF due to specific features of the DVB-T signal, as guard intervals and pilots. The performance of the conceived filter is evaluated against simulated data and compared to other existing approaches. It is shown to yield more robust performance in terms of CAF improvement with reduced computational load and system complexity.
