Abstract Opportunistic array radar is a new radar system that can improve the modern radar performance effectively. In order to improve its radio frequency stealth ability, a novel coordination method of opportunistic array radars in the network for target tracking in clutter is presented. First, the database of radar cross section for targets is built, then the signal-to-noise ratio for netted radars is computed according to the radar cross section and range of target. Then the joint probabilistic data association algorithm of tracking is improved with consideration of emitted power of the opportunistic array radar, which has a main impact on detection probability for tracking in clutter. Finally, with the help of grey relational grade and covariance control, the opportunistic array radar with the minimum radiated power will be selected for better radio frequency stealth performance. Simulation results show that the proposed algorithm not only has excellent tracking accuracy in clutter but also saves much more radiated power comparing with other methods.

Modified Cramér‐Rao lower bounds for joint position and velocity estimation of a Rician target in OFDM‐based passive radar networks

“…Recently, extensive research [ Chen et al , ; Daout et al , ; Gogineni et al , ; Griffiths and Long , ; Howland et al , ; Stinco et al , ] has been conducted in passive radar systems that utilize illuminators of opportunity owing to their advantages of low implementation costs, low probability of intercept [ Shi et al , , ; Zhang et al , ], and so on. The two‐dimensional target localization problem is investigated for the WiFi‐based multistatic passive radar [ Falcone et al , ], and different target localization schemes are proposed based on different sets of available measurements.…”

Joint Dwell Time and Bandwidth Optimization for Multi-Target Tracking in Radar Network Based on Low Probability of Intercept

“…With the development of passive detectors, such as the radar warning receiver (RWR), electronic warfare support (ES), anti-radiation missile (ARM), and so on, a serious threat is posed to the radar network. As a result, the study of LPI optimization for radar network systems has attracted significant interest in recent years [18][19][20][21][22][23]. She et al [21] proposed a sensor selection and power allocation algorithm for multi-target tracking, whose basis is to reduce the total transmitted power under the constraint of target tracking accuracy, with the purpose of improving the LPI performance of the radar network.…”

Adaptive Jamming Waveform Design for Distributed Multiple‐Radar Architectures Based on Low Probability of Intercept

“…Nowadays, the concept of low probability of intercept (LPI) should be taken into account in designing radar systems (Pace, ; Schleher, ; Shi et al, ; Shi, Zhou, & Wang, ; Zhang et al, ). Precisely, large revisit interval, low transmission power, short dwell time, ultralow sidelobe antenna, and waveform optimization can result in better LPI performance of radar system.…”
