Detection of singular corner reflectors in residential and mountainous areas from SAR images

Abstract

In a mountainous and highly populated country like Japan, corner reflectors frequently must be placed near confounding objects. A procedure to detect singular corner reflectors in such situations is described. It is found that the initial reduction of speckle by the Enhanced SFP filter greatly facilitated the detection of these corner reflectors from both JERS-1 SAR images and ERS-2 images.
