Abstract :
In this study, the problem of low probability of identification (LPID) performance improvement for distributed multiple-radar system (DMRS) is addressed. Firstly, we propose security information factor originating from secrecy capacity to evaluate the LPID performance for DMRS, and derive an explicit closed-form expression of security information factor. Then, a novel LPID enhancement scheme based on security information factor is presented, whose purpose is to maximize the achievable security information factor by optimizing the transmission waveforms and the cooperative jamming spectra with the predefined total transmission energy and cooperative jamming power constraints. Numerical simulations demonstrate that the proposed strategy can effectively achieve the optimal solutions and bring remarkable improvement on the LPID performance for DMRS.
