Simultaneous AJ and LPD Evaluations for Secure Communication

In this paper, a systematic approach for evaluating the interactions of the link geometry for anti-jamming, low probability of detection, and their combined applications are investigated. In many typical cases, communication designs have to deal simultaneously with adversary threats of both active jamming and passive detection. And by increasing communication power to counter jammer and enhancing anti-jamming (AJ) capability must be weighted carefully against the increased threats of deteriorating low probability of detection (LPD) capability and being detected by an unintended interceptor receiver. A qualitative and quantitative approach with sinc-type antenna patterns being included for evaluating both AJ and LPD concurrently is reached. And it is intuitive to see that by spreading signal spectrum, complicating signal waveforms, and lowering power control uncertainty, respectively, will enhance system performance accordingly.
