摘要：

Previously unreported phenomena of distributed target multipath observed with passive radar systems are presented and discussed. Trail-like signatures in the range-Doppler surface are shown from UHF Digital Television passive experimental trials with commercial airliner targets. Simulated results for distributed ground multi-bounce paths demonstrate a high degree of similarity to the empirical observations, validating the cause of this atypical range-Doppler response. Both experimental and simulated results demonstrate the phenomenology which can arise as a result of the multi-bounce distribution, such as Doppler expansion and inversion. Potential methods for exploiting the multipath components to improve radar system performance are also discussed.
