Abstract

In this paper we introduce the mean-square-error correlation filter for obscured targets. We derive from this algorithm that the DC-blocked phase-only filter is the best practical approximation to this filter for recognizing SAR images with enhanced scattering centers for both inputs and templates. The performance of the DC-blocked phase-only filter is tested in the recognition of SAR images from the MSTAR data base under extended and non-extended operating conditions. The heterogeneous correlation filter algorithm used to correlate totally different images is utilized to correlate distorted images under extending operating conditions.
