Study of Multistatic Radar Against False Targets Jamming Using Spatial Scattering Properties

Abstract

This paper presents a discrimination method of deception false targets in multistatic radar system using signal fusion. Based on the difference in spatial scattering properties between physical targets and false targets, correlation test is used on the complex envelope sequences to identify false targets, which is formulated as a problem of likelihood ratio test in the NeymanPearson sense. The simulation results verify the efficiency of the approach to discriminate false targets on the premise of the acceptance probability of physical targets.

A study on finite false target jamming for radar track generation

“…However, for radar with multitarget detection and tracking capability, the protected real target can still be detected by the radar and form an effective track. Simultaneously, radar may use active/passive radar based on distributed architectures [8] , waveform agility [9] , and measurement fusion methods for radar networks [10] . For suppression jamming [11] , noise or noise-like jamming signals are mostly used to cover or suppress the target echo signals.…”

Adaptive optimization technology of segmented reconstruction signal based on genetic algorithm for enhancing radar jamming effect

“…By treating waveform parameters, such as false target positions and amplitudes, as genes, the jammer can iteratively modify them to minimize an objective function associated with jamming effectiveness, such as reducing detectable false targets. Genetic algorithms facilitate exploration of the vast solution space to identify jamming waveforms that effectively counter specific radar detection schemes [20][21][22][23].…”
