Abstract

An experimental adaptive digital pulse compression (ADPC) subsystem is described. This unit implements a complex correlation between a stored replica of the transmitted waveform and the signals received by the radar. Key to the adaptability of this unit is the use of high-speed VLSI digital ICs which permit bandwidths of up to 10 MHz, along with its ability to use a different waveform or pulse code on each transmission. The ADPC system has been evaluated using both polyphase and binary phase codes in the presence of thermal noise and interference from other waveforms which are not matched to the current transmission
