Abstract:A new method for modeling and simulation of coherent k-distributed clutter is presented. Compared with ZMNL and
SIRP, this method can generate coherent clutter with arbitrary complex ACF, and it doesnt need resolving non-liner equation and matrix
inverse. As a result the speed of simulation is improved markedly. The results from simulation prove the validity of this scheme.
Key words: clutter modeling; k-distributed; coherent; non- Gaussian
