Abstract : Pulse-Doppler processing is an often used technique for extracting range and Doppler information of targets. Such a system can be described as consisting of three basic components, a pulse compressor, sampler, and Doppler processor. When quadrature detection is used, the gains and timing of the sampled inphase and quadrature components of the pulse compressor output must be matched in order to minimize distortion and noise at the Doppler processor output. In addition, the jitter in the sampling times also caused distortion and noise. This report presents an analysis of these effects and describes the signal degradations due to mismatch and jitter in the sampler. (Author)
