Abstract :
The non-stationary nature of high resolution grazing angle X-band radar backscatter of the sea surface is investigated. The temporal behavior is modeled as resulting from a fast and a slow process, and statistical parameters are derived for both processes separately. It is found that the fast process is consistent with an underlying complex Gaussian process, independent of polarization or range resolution, while the slow process is responsible for the spiky nature of the HH backscatter
