A STUDY OF RADAR PULSE COMPRESSION USING COMPLEMENTARY SERIES TO MODULATE THE TRANSMITTED WAVEFORM.
Abstract
Pulse compression radars have resulted from the need to put more energy into a transmitted pulse by increasing the pulse duration, yet retaining or improving the target range resolution. FM chirp and phase-coded pulse compression using a single binary code to modulate the carrier are somewhat degraded by the amount of hash, or range sidelobes in the output of the matched-filter receiver. Pulse compression using complementary series, in which two binary series are transmitted, results in no range sidelobes in the detected pulse, since the autocorrelation functions of the two series completely cancel each other everywhere except at zero shift, where they add to produce a sharp peak with amplitude 2N times the received pulse amplitude, where N is the number of digits in each series. After introductory material on complementary series and pulse-compression systems, the thesis discusses the design, construction and testing of a pulse-compression system using complementary series of length four. The intent was to show feasibility, rather than to produce results using actual targets. (Author)
