Abstract :
Bi-static ISAR has many advantages compared to mono-static ISAR. In this paper, we describe the bi-static ISAR signal model, range resolution and Doppler resolution; discuss coherent processing of reflected signals at the receiver site to produce ISAR range-Doppler images of moving targets; and analyze bi-static Doppler and micro-Doppler features of target motions. We use simulated bi-static radar data to generate ISAR images of moving targets and extract bi-static micro-Doppler features.
