Abstract :
Discusses clutter simulation which is an important element in the development of target detection algorithms for radar remote sensing. SAR images are well represented by the K distribution and an important feature of SAR clutter is the autocorrelation function. Methods are described for the generation of realisations from a correlated K distribution with specified correlation properties. Higher order correlations are also considered
