Abstract : A waveform generator particularly suited for the simulation of Doppler radar returns from precipitation is provided. Also, waveform pattern selected capability is provided and spectral shapes such as Gaussian distributions, symmetrical and asymmetrical bimodal spectral shapes or flat spectra can be chosen and generated. The device is portable and capable of being used in the field. The purpose of simulating such returns is so that a weather radar receiver and its associated circuitry can be accurately calibrated and tested. Moreover, the device presented herein may be employed to generate various dynamic weather patterns for training purposes.
