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.

IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.This paper proposes a radar intra‐pulse modulation recognition method based on the transformer architecture, named RBViT. By designing multi‐scale input embeddings and introducing a novel position encoding based on radial basis functions (RBF), the algorithm significantly enhances recognition performance under a low signal‐to‐noise ratio (SNR ...

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.
