Abstract :
Carrier-free coded waveforms that promise good clutter rejection and high-resolution capabilities for radar are represented as a sequence of positive and negative Gaussian pulses. On the basis of this signal representation, the matched-filter (or correlated receiver) response to carrier-free coded waveforms is analyzed and plotted for certain Barker and complementary codes, complementary-code pairs being the optimum codes for clutter rejection. The systematic design of a carrier-free, pulse-compression radar system is described. A correlator receiver that is specifically designed for the selective reception of complementary-code pairs is presented. Computer simulation results for the correlator receiver are also presented
