Abstract

We investigate passive radar imaging of aircraft using reflected TV signals. We apply a smoothed pseudo Wigner-Ville distribution (SPWVD) based SAR imaging algorithm to two different scenarios. In the first simulation, a multistatic VHF-band dataset generated by fast Illinois solver code (FISC) is used. In the second simulation, a more realistic simulated passive radar dataset is used. A set of instantaneous images is produced by our algorithm. They have higher resolution and show more detail and features of the aircraft than can be obtained by direct Fourier reconstruction (DFR). The set of images provides more visual information about the target and helps to estimate its shape and features. This study suggests that the SPWVD-based imaging might be useful in passive radar imaging and target classification
