The low probability of intercept radar systems with spatial feedback
IEEE EUROCON 2009, 2009“The radar system with spatial positive feedback throw the target is considered. In this system there are self-oscillations, if the system is closed through a space of the signal radio-path and the target. When the target is absent (system is not closed), transmitter output power of the noise signal is insignificant, and that complicates detection of ...

The analysis and design of modern Low Probability of Intercept radar
2001 CIE International Conference on Radar Proceedings (Cat No.01TH8559), 2002In the modern battlefield, radar faces more and more serious threats from ECM and ARM, etc. Only the Low Probability of Intercept (LPI) radar can survive. In this paper, the principle of LPI radar is introduced first. Then the effects of radar parameters on LPI performance are discussed in detail.

Radar signal processing development for low probability of intercept radar system
2016 IEEE Region 10 Conference (TENCON), 2016In 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

Adaptive radar jamming waveform design based on low probability of intercept
2015 IEEE China Summit and International Conference on Signal and Information Processing (ChinaSIP), 2015Low 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 ...

Low Probability of Interception of an Advanced Noise Radar Waveform with Linear-FM
IEEE Transactions on Aerospace and Electronic Systems, 2013This research considers an advanced pulse compression noise (APCN) radar waveform possessing salient features from linear-FM (LFM) and noise waveforms. A cross-correlation model considering several chirp waveform profiles is used to simulate the output of a passive electronic intelligence (ELINT) intercept-receiver.

Low Probability of Intercept Radar Signal Recognition by Staked Autoencoder and SVM
2018 10th International Conference on Wireless Communications and Signal Processing (WCSP), 2018A novel low probability of intercept (LPI) radar signal recognition method based on stacked autoencoder combined with support vector machine (SVM) is proposed in this paper. The method firstly transforms the LPI radar signal to time-frequency $(\mathrm{T}-\Gamma)$ domain through Choi-Williams Distribution (CWD) to obtain the T-F images of signals. Then,
