Optimal Power Allocation Algorithm for Radar Network Systems Based on Low Probability of Intercept Optimization(in English) [PDF]

open access: yesLeida xuebao, 2014
A novel optimal power allocation algorithm for radar network systems is proposed for Low Probability of Intercept (LPI) technology in modern electronic warfare. The algorithm is based on the LPI optimization.

Spatial Information-Theoretic Optimal LPI Radar Waveform Design [PDF]

open access: yesEntropy, 2022
In this paper, the design of low probability of intercept (LPI) radar waveforms considers not only the performance of passive interception systems (PISs), but also radar detection and resolution performance. Waveform design is an important considerations

A fast Wigner Hough transform algorithm for parameter estimation of low probability of intercept radar polyphase coded signals [PDF]

open access: yesIET Signal Processing, 2023
It is difficult for a receiver to intercept the signals from a radar system that can emit low probability of intercept (LPI) polyphase coded signals. The traditional Wigner Hough transform (WHT) algorithm requires a large amount of computation and takes ...

Bearing estimation of low probability of intercept sources via polynomial matrices and sparse linear arrays [PDF]

open access: yesIET Radar, Sonar & Navigation, 2021
Recent years have seen a steady convergence of Radar and Communications band Radio Frequency (RF) transceiver systems. Not only have Communications systems colonised large swathes of previously allocated Radar bands but there is also a convergence of ...

Signal design and processing for noise radar

open access: yesEURASIP Journal on Advances in Signal Processing, 2022
An efficient and secure use of the electromagnetic spectrum by different telecommunications and radar systems represents, today, a focal research point, as the coexistence of different radio-frequency sources at the same time and in the same frequency ...
