LPI based resource management for target tracking in distributed radar network

This paper presents a novel low probability of intercept (LPI) based resource management algorithm for target tracking in distributed radar network, which consists of a dedicated radar netting station and multiple netted radars. Firstly, the intercept probability for radar network is calculated. Then, an adaptive resource management scheme based on LPI is formulated, in which a novel objective function for LPI performance is defined and minimized by optimizing the revisit interval, dwell time, and transmitting power in radar network to guarantee a predetermined target tracking accuracy with passive time difference of arrival (TDOA) cooperation. The performance of the proposed algorithm is validated by Monte Carlo simulations.
