Abstract: This paper describes a method for computer simulation of radar clutter. A Gaussian spectrum is used as the model of radar clutter. The table look ?up method is used for rapidly generating two series of Gaussian random numbers,which are independent and orthogonal to each other .Gaussian random numbers with Gaussian spectrum which simulate radar clutter are rapidly generated through the low order recursive digital Gaussian filter. A set of statistical tests,correlation and spectral analysis are then perf orined.Tbese random numbers,which are rapidly generated with satisfactory accuracy, cap be used as the clutter environment of a radar and with them satisfactory results have been obtained in the simulation of radar moving target detection systems.
