Deep Learning Approach to LPI Radar Recognition

, 2019
In this study, an advanced automatic low probability of intercept (LPI) radar recognition technique (LWRT) that includes both LPI radar signal classification and parameter extraction is proposed. It is shown with Monte Carlo simulation that, even without

Radar Signal Recognition Based on CSRDNN Network

IEEE Access
It is essential to achieve the high-accuracy recognition of low probability of intercept (LPI) radar signals in modern electronic warfare. However, under low signal-to-noise ratio (SNR), the recognition accuracy of the LPI radar signals is relatively low.

Non-cooperative game-theoretic distributed power control technique for radar network based on low probability of intercept

, 2018
Here, the problem of non-cooperative game-theoretic distributed power control is studied in a radar network system based on low probability of intercept (LPI) subject to the signal-to-interference-plus-noise ratio (SINR) constraint and the transmit power

Low Probability of Intercept (LPI)

, 1998
Low probability of intercept (LPI) is the term used for there being a low probability that a radar's emissions will be usefully detected by an intercept receiver in another aircraft or on the ground. For the air battle of the future, LPI is essential. In conventional aircraft the most important need for LPI is to avoid electronic countermeasures.

Waveform design for MIMO radar with low probability of intercept (LPI) property

2011 IEEE International Symposium on Antennas and Propagation (APSURSI), 2011
A 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.
