Correlators

Abstract

Three commonly employed types of cross correlators were designed using standardized components which closely simulate idealized elements in an effort to experimentally verify the theoretical analysis. These cross correlators are (1) the standard analog cross correlator which consists of bandpass filters, a multiplier and a postmultiplier lowpass filter, (2) the polarity coincidence correlator (PCC) which utilizes a hard clipper in each input channel, and (3) a modified type of PCC which features a hard clipper in only one of the input channels. Two different types of filters viz. (1) the seventh-order Butterworth lowpass filter, and (2) the five-pole Chebyshev lowpass filter with a maximum passband loss of 1 dB were utilized. The output signal-to-noise ratio (SNR) was experimentally computed as a function of input signal-to-noise ration and compared with theoretical predictions. The performance in terms of output SNRs of the three cross correlators are compared. In all cases, the experimental results were in close agreement with the theoretical models.
