A method and system that include a first measurement signal and a second measurement signal that can be input to first and second filters. The filters can be subject to a first constraint to minimize the energy difference between the first and second measurement signals on a per frequency basis, and subject to a second constraint that includes a model frequency and phase response. By adapting the filters subject to the two constraints, coherent differences between the two measurement signals can be identified. In one embodiment, the system can be applied to Synthetic Aperture Radar (SAR) data.
