Abstract

Direct Sequence Spread Spectrum (DSSS) signals are commonly used for a variety of applications including radar, positioning and communications. Under certain circumstances, a jammer can used as a counter measure to DSSS systems. One of the several jamming mechanisms is the use of chirp signals. In this paper, we investigate the jamming performance of chirp signals which linearly sweep a certain bandwidth in a certain period on DSSS. We demonstrate that jamming performance of the chirp signal depends on both the parameters of the jammer and also to the period of the DSSS signal and the Pseudorandom Noise (PN) sequence which is used to generate the DSSS signal. Rules for designing a chirp jammer are also provided. Results of experimental trials are also discussed.
