摘要：

This paper provides a detailed overview of Digital Video Broadcasting Terrestrial (DVB-T) signal structure and the implications for passive radar systems that use these as illuminators of opportunity. In particular, we analyze the ambiguity function and make explicit its features in delay and Doppler in terms of the underlying structure of the DVB-T signal. Ambiguities will be managed via the development of a set of mismatched filter weights that will be applied to the reference signal prior to range-Doppler map formation. The development of the mis-matched filter is based on previous work with an extended improvement for ambiguity peak reduction a wider variety of DVB-T signals.
