Abstract :
We propose a segment averaging matched-filter solution for recovering radar phase history data from orthogonal frequency division multiplex (OFDM) signals. The impact of digital communication features-guard bands, preambles, pilots, sync symbols, and cyclic prefixes-is discussed, and the derived matched-filter solution is modified accordingly. Experimental images using generic OFDM and IEEE 802.16 WiMAX signals demonstrate the success of the proposed signal processing approach for passive bistatic radar imaging.
