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

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,

Low Probability of Intercept Radar Signal Recognition Based on the Improved AlexNet Model
Proceedings of the 2nd International Conference on Digital Signal Processing, 2018In order to solve the problem that low recognition rate and less signal type of low probability of intercept (LPI) radar signal at -6dB of low signal-to-noise ratio (SNR), the paper presents a method based on Smooth Pseudo Wigner-Ville distribution (SPWVD) for signal time-frequency analyze and an improved-AlexNet deep convolutional neural network (DCNN)

Phenomenology of low probability of intercept synthetic aperture radar via Frank codes
SPIE Proceedings, 2014This paper investigates techniques for using low probability of intercept (LPI) modulation techniques for forming synthetic aperture radar (SAR) imagery. This analysis considers a specific waveform type based upon Frank codes in providing for the LPI capability via phase shift keying (PSK) modulation.

Bistatic Radar and Low-Probability-of-Intercept Radar
2004This discussion of the fundamentals of bistatic radar follows that of Willis, who provides a history of many bistatic radar proposals and programs and a summary of many technical analyses. Figure 13.1 introduces some basic terminology. Instead of two locations of interest (the radar and the target), we now have three (transmitter, Tx; receiver, Rx; and

Low probability of intercept (LPI) techniques and implementations for radar systems
Proceedings of the 1988 IEEE National Radar Conference, 2003After a brief overview of optimal low-probability of intercept (LPI) radar design criteria, it is shown that for a given radar signal code length, many more codes are available by using higher-order Galois fields; that is, polyphase coding will supply the required diversity. Various aspects of polyphase coding are described because Doppler compensation

Implementation of Plan Position Indicator Display for Low Probability of Intercept Radar
2018 International Conference on Radar, Antenna, Microwave, Electronics, and Telecommunications (ICRAMET), 2018This 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 ...

Waveform design for MIMO radar with low probability of intercept (LPI) property
2011 IEEE International Symposium on Antennas and Propagation (APSURSI), 2011A joint waveform and array signal processing approach is proposed to minimize MIMO radar antenna radiation power for best low probability of intercept (LPI) property in pre-selected directions and to achieve near-optimum target detection simultaneously. Some simulation results are presented.
