Technique for target detection and rangingbased on broadband LPI radars
Electronics Letters, 2001 A processing technique for improving the ranging and detection capabilities of LPI radars and the measured performance of an experimental system are presented. The precision of the measured distance is very high even under low SNR conditions. The associated detection algorithm also exhibits good performance in noisy environments.

Design and Processing of a Novel Chaos-Based Stepped Frequency Synthesized Wideband Radar Signal
Sensors, 2018 The linear stepped frequency and linear frequency shift keying (FSK) signal has been widely used in radar systems. However, such linear modulation signals suffer from the range–Doppler coupling that degrades radar multi-target resolution.

Digital signal generation for LFM–LPI radars
Electronics Letters, 2003 A new algorithm to generate chirp signals with low computational complexity and very low memory is presented. This algorithm, based on a feedback and time-variant system, can improve the chirp signal generation typically used in LPI radar with lineal FM.

Modeling and Analysis of LPI Radar Signal
IOSR Journal of Electronics and Communication Engineering, 2013 Radar Emitter Signal recognition is one of the key procedures of signal processing in Electronic Warfare (EW) Receiver. As there is an intense growth in the activities of modern Electronic Warfare, advanced radars are increasing and becoming main component of radars gradually. These modern radars called Low Probability of Intercept (LPI), use different

A NOVEL LPI METHOD OF RADAR'S ENERGY CONTROL
Progress In Electromagnetics Research C, 2012 A novel radar energy control strategy based on an improved Interacting Multiple Model Particle Filter (IMMPF) tracking method is presented in this paper. Firstly, the IMMPF tracking method is improved by increasing the weight of the particle which is close to the system state and updating the model probability of every particle.
