Experimental results of high-resolution ISAR imaging of ground-moving vehicles with a stationary FMCW radar

Abstract

In the paper experimental results of ISAR (Inverse Synthetic Aperture Radar) processing obtained with high-resolution radar are presented. Targets under observation were ground moving vehicles, such as cars, trucks and tractors. The experiments were performed with a FMCW (Frequency-Modulated Continuous-Wave) radar operating at 94 GHz with almost 1 GHz of bandwidth. Due to the measurement scenario more typical for SAR (Synthetic Aperture Radar), than ISAR, i.e. targets moving along straight line crossing the antenna beam, algorithms usually applied for SAR processing have been used.
