Radar target doppler frequency scintillation simulator and method

摘要

Generating five Gaussian random variable, statistically identical but independent, signals, squaring four of the signals and combining two or four of the signals to provide the target power return, or radar cross section, of Swerling case one or three targets, respectively. Utilizing the fifth Gaussian random variable and dividing it by the square root of the target power return signal, and multiplying the result by the bandwidth of the fifth Gaussian random variable and a scale factor to provide an output signal representative of the target Doppler frequency scintillation.
