摘　　要：本文讨论了一种幅度满足双瑞利分布，其二维谱和特征值谱给定的时空二维杂波的模拟方法，它对机载相控阵雷达系统的设计和性能分析是极有意义的．文中详细探讨了二维杂波模拟遇到的新问题，并提出检验二维杂波模拟结果的新要求．In this paper,we discuss a method of generating the 2-D complex random sequence with power spectrum and eigenspectrum approximated to given power spectrum and eigenspectrum,and with amplitude obeyed to the bimodal Rayleigh distribution. The method is very useful in the design and performance estimation of airborne phased array radar system.Here,some new problems which exist in the procedure of generating 2-D clutter are explored in detail,and a new requirement of testing 2-D clutter is given.
