Low probability of intercept radar strategies
IEE Proceedings - Radar, Sonar and Navigation, 2004 To reduce probability of intercept, in most cases, the form and magnitude of the radar transmissions are designed to spread energy over as wide a range of dimensions as possible. Equally, in response to this, designs for electronic surveillance measures (

A low probability of intercept OFDM radar communication waveform design method [PDF]
2021 IEEE International Conference on Consumer Electronics and Computer Engineering (ICCECE), 2021 In recent years, orthogonal frequency division multiplexing (OFDM) has been widely used as a radar communication integrated shared signal. In order to improve the RF stealth performance of OFDM radar communication integration system, a shared waveform ...

Detection and classification of Low Probability of Interception (LPI) radar signals is one of the most important challenges in electronic warfare (EW), since there are limited methods for identifying these type of signals. In this paper, a radar waveform automatic identification system for detecting and classifying LPI radar is studied, and accordingly

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}

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)

Radar sensor using low probability of interception SS-FH signals
IEEE Aerospace and Electronic Systems Magazine, 2000 One of the best known weakness of radar sensors in defense and security applications is the necessity to radiate a signal, which can be detected by the target, so being possible (easy in fact) that the target is alerted about the presence of a radar before the radar is alerted about the presence of a target.

Encrypted Waveform Design for Low-Probability of Intercept Radar
2024 9th International Conference on Signal and Image Processing (ICSIP)In this paper, a novel encrypted waveform employing pseudo-random binary phase sequence (PRBPS) is introduced, which effectively disguises a regular waveform by presenting it with chaotic parameters.
