Deep Learning Approach to LPI Radar Recognition
2019 IEEE Radar Conference (RadarConf), 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 the unrealistic assumptions used in the previous studies, the proposed LWRT achieves classification

Methods for Analysis of LPI Radar Signals
2006 IEEE 14th Signal Processing and Communications Applications, 2006 LPI (Low Probability of Intercept) radars occupy wide frequency bands and have very low peak power so they are difficult to be detected by hostile intercept receivers. Hostile radiometric receivers are not able to intercept and measure the parameters of LPI signals which lie in wide frequency bands.

, 2023 This dissertation is for researching the feasibility of a Low Probability of Intercept (LPI), Air Defence (AD) Noise Radar with high range and doppler resolution. The research is approached by first simulating an S-Band LPI Noise Radar detecting a flying target and determining its range and velocity. The simulated Noise Radar is then implemented in the

Automatic Intrapulse Modulation Classification of Advanced LPI Radar Waveforms
IEEE Transactions on Aerospace and Electronic Systems, 2017In this paper, improved signal processing techniques are developed for the analysis and classification of low probability of intercept (LPI) radar waveforms. The intercepted LPI radar signals are classified based on the type of pulse compression waveform.

Anti-Jamming and LPI Radar with Spread Spectrum Technology
Advanced Materials Research, 2011 In order to enhance the capability of anti-jamming and Low Probability of Intercept (LPI) of radar system, spread spectrum signals are designed for modern radar system. Emission signal is coded with PN codes at the transmitting terminal. Spectrum of signal is spreaded and multi-signal mixed together, so it is not easy to intercept.

Interception of LPI radar signals
IEEE International Conference on Radar, 2002The interception problem is reviewed, an LPI radar design is examined and the performance of intercept receivers of the future is considered. The receiver needed to intercept LPI signals must respond across a broad band and provide noncoherent integration capabilities over times comparable to the coherent (or noncoherent) integration times used by ...

A Novel Method to Detect and Localize LPI Radars
IEEE Transactions on Aerospace and Electronic Systems, 2019In this study, a new passive method suitable for geolocating low probability of intercept (LPI) radars is introduced. The method uses two electronic support receivers placed on a fast moving platform (e.g., an airplane or a satellite). The proposed method has a high processing gain, which makes it highly suitable for very weak LPI signals.
