An optimal sampling of linear FM signal for efficient aperiodic correlations

Abstract

In digital communication and radar pulse signal processing, sequences with low autocorrelation levels are highly desirable. It has become a common practice to perform signal processing in discrete structures instead of continuous domains. The discrete structure of the phase code signal implies a possible potential to manipulate sidelobe patterns as desired, which promises wide dynamic range responses for various applications. This paper shows that a particular sampling rate for linear FM signals may lead to a significant reduction of peak sidelobe level (PSL) at the pulse compression output
