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)

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 ...

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

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.

Adaptive detection for low probability of intercept radar signals and FPGA implementation
This Letter presents an adaptive detection algorithm based on dynamic dual-threshold for low probability of intercept (LPI) radar signals in complex electromagnetic environments. The algorithm dynamically estimates background noise to effectively suppress interference spikes and prevent signal splitting.Xiaoji Wei +3 more
