Abstract

This paper analyzes the effects of range and Doppler walk for a Digital Video Broadcast - Terrestrial based Passive Bistatic Radar of both simulated and experimental data. Range and Doppler walk cause energy dispersal in the correlation, thus the coherent integration time is limited by the bistatic velocity and acceleration. A method using the readily available Doppler information to compensate for the range displacement during integration due to non-zero bistatic velocity of target is described. By compensating and non-coherently adding several coherently processed intervals, the target signal to noise ratio is increased.
