Ameliorated simulation method of compound K-distributed clutter

To solve the question which is not considered for the realizable linear filter of physics in the simulation of compound K-distributed clutter at present, the statistics characteristic of the clutter model and simulation method of ZMNL (Zero Memory Nonlinearity) were firstly studied. Then adopting minimum phase feature and complex cepstrum technology, the technique of the realizable filter of physics was proposed based on these. Furthermore, the method of generation of random K-distributed sequences was put forward profoundly. Finally, the simulation was processed and the results prove both validity and veracity of the method. The clutter generated by this method can be used in the simulation of radar signal, analysis of radar image and optimization of radar signal processor.
