Power control and beamforming in passive phased array radars for low probability of interception

Digital Signal Processing, 2021
Abstract In this paper, we investigate low probability interception (LPI) in passive phased array radars. Power control and transmit beamforming (BF) are used to minimize the received power by the interceptor. Meanwhile, desired target detection performances and the limited power budget of radar are guaranteed.

Radar signal processing development for low probability of intercept radar system

2016 IEEE Region 10 Conference (TENCON), 2016
In this paper, researches on the development of a low probability of intercept (LPI) radar is presented. This radar was developed based on the existing frequency modulated-continuous wave (FM-CW) coastal surveillance radar at the PPET-LIPI. This LPI radar development was initiated by modifying the antenna design to produce more perfect beams, where the

Implementation of Plan Position Indicator Display for Low Probability of Intercept Radar [PDF]

2018 International Conference on Radar, Antenna, Microwave, Electronics, and Telecommunications (ICRAMET), 2018
This paper describes the steps of developing a Plan Position Indicator (PPI) radar display to be used on military ships. The PPI radar display system is a display of radar data in a polar coordinate representation. The PPI radar display is one of the most critical parts of the radar system, which provides information of the detection results of radar ...

Low probability of intercept optimization for radar network based on mutual information

2014 IEEE China Summit & International Conference on Signal and Information Processing (ChinaSIP), 2014
This paper investigates the problem of low probability of intercept (LPI) design for radar network system and presents a novel LPI optimization strategy based on mutual information (MI) to improve the LPI performance for radar network. With the radar network system model, this paper would first derive Schleher intercept factor for radar network.

Low Probability of Intercept Radar Signal Classification using Multi-Channel 1D-CNN

International Conference on Cryptography, Security and Privacy
Modern radar systems are designed to emit low probability of intercept (LPI) waveforms to avoid interception and detection by enemies. In this process, automatic radar LPI waveform recognition becomes a helpful tool for electronic counter-measures.

Adaptive radar jamming waveform design based on low probability of intercept

2015 IEEE China Summit and International Conference on Signal and Information Processing (ChinaSIP), 2015
Low probability of intercept (LPI) has currently become a central issue in modern electronic warfare. In this paper, the problem of task-dependent adaptive radar jamming waveform design based on LPI is investigated. Firstly, the achievable signal-to-interference-plus-noise ratio (SINR) and mutual information (MI) are derived to evaluate the target ...
