Abstract
We describe an extensive data collection and analysis of change detection using VHF- and UHF-band SAR data. Two airborne systems (CARABAS-II: 22–82 MHz, LORA: 225–470 MHz) acquired data for multiple headings and incidence angles. Twenty one targets of five types were deployed in forest concealment. CARABAS-II gives the best performance for the target types investigated. Analysis of the data shows that performance degrades for increasing incidence angle, mainly due to reduced target radar-cross section. It is also shown that different change detectors give different performance. The best detector for one incidence angle is not necessarily best for another incidence angle.
