Prediction of coherent change detection performance in SAR

A method of Coherent Change Detection (CCD) performance prediction is described based on (1) a simple analysis of the frequency support overlap between the two collects which encapsulates imaging geometry effects and (2) a method of relating environmental effects to average scatterer disturbance which can be assessed empirically. The strength of this approach is that, once the average disturbance for a particular environmental effect has been established from one system, it can be extrapolated to all other systems since mean disturbance is system-independent. Validation and application of this approach using simulated examples is presented.
