Abstract
This paper presents a constant false alarm rate (CFAR) target detection scheme in ground clutter at W-band (94 GHz), making use of clutter decorrelation bandwidth and co- and cross-polarized received data. The scheme, based on the concept of a CFAR matched subspace detector, yields a CFAR with respect to clutter amplitude distribution. In order to investigate the detection performance, we carried out a Monte Carlo simulation and experiments using the W-band stepped-frequency polarimetric radar system. The results are also compared with the conventional CFAR detector.
