Abstract: The information of low probability interception (LPI) signals is useful in practice,but LPI signals are often hided or put in jammer,which show more difficulty in direction-finding.This paper exploits the characters of signals and uses spectral correlation theory in direction-finding of LPI signals in jammer.The simulation results show that the combination of array direction-finding and spectral correlation theory can get better results than the method of MUSIC in direction-finding of LPI signals.
