Abstract

This paper investigates the low probability of intercept (LPI) performance optimization for an integrated multistatic radar and communication (IMRC) system, which is composed of multiple transmitters operating at different frequencies, a radar receiver (RR) and a communication receiver (CR). The IMRC system is capable of fulfilling the requirements of both radar and communication sub-systems. The basis of the LPI optimization strategy is to minimize the total radiated power by optimizing the power resource allocation at each transmitter for radar waveforms and information signals, which is constrained by a predetermined target detection performance for the RR and a desired information rate for the CR. Subsequently, the resulting optimization problem is solved by an efficient solution procedure based on the approach of linear programming and the Karush-Kuhn-Tuckers (KKT) optimality conditions. Numerical results demonstrate the effectiveness of the proposed algorithm.
