Radar power control method based on IMM-IF in LPI radar network
2016 CIE International Conference on Radar (RADAR), 2016In order to achieve the important tactical requirement of low probability of intercept (LPI) in the radar network, dynamically controlling the emission of the radars is very necessary. Firstly, a data fusion method based on an interacting multiple model and information filtering (IMM-IF) algorithm is presented.

A novel method for LPI radar signal sorting in multipath channel
2012 IEEE International Symposium on Industrial Electronics, 2012Signal sorting of low probability of interception (LPI) radar signals is extremely important in electronic support measurement (ESM) systems. Usually, there are multipath interferences in the intercepted signals, which result in the decrease of signal sorting performance of conventional methods. In this paper, we present a local ambiguity function (AF)-

Using wavelet packets to analyze FM LPI radar signals
2016 IEEE Sensor Array and Multichannel Signal Processing Workshop (SAM), 2016The FM (Frequency Modulated) LPI (Low Probability of Intercept) radars, unlike conventional radars, transmit a long or a continuous signal, with low power, using causal modulation. These LPI radar characteristics make it virtually invisible to conventional RWRs (Radar Warning Receivers) and ESM (Electronic Support Measures) receivers.

Mutual information–based LPI optimisation for radar network
International Journal of Electronics, 2014Radar network can offer significant performance improvement for target detection and information extraction employing spatial diversity. For a fixed number of radars, the achievable mutual information (MI) for estimating the target parameters may extend beyond a predefined threshold with full power transmission.

Target assignment and power allocation for LPI radar networks
2015 The International Symposium on Artificial Intelligence and Signal Processing (AISP), 2015In this paper, power allocation and target assignment is considered as a promising way to obtain low probability of interception (LPI) in the radar network. Spatial diversity in the netted radars gives us a flexibility to control power intelligently and radar assignment dynamically in such a way that not only detection performances satisfied but LPI ...

Detection and Parameter Estimiation of LPI Signals in Passive Radar
2006 CIE International Conference on Radar, 2006It is desired for multi-static passive radar to intercept target radar signals simultaneously during the process of location which utilize the difference time of arrival (DTOA). However, many LPI techniques are adopted by airborne radar in practice such as low side lobe method and narrow beam technique.
