A deceptive jamming technique against bistatic SAR

In recent years, radar jamming systems have become a crucial research area in the field of remote sensing for defence and security tasks. In a multistatic Synthetic Aperture Radar (SAR), the presence of false targets created by a deceptive jammer is recognizable thanks to the presence of multiple receivers, whose positions might not be easily known by the jammer. In this configuration the bistatic SAR geometry can be designed so that false targets are kept out observed bistatic scene. In this paper, we propose a mathematical analysis that expresses the jammer’s delay parameter as a function of the bistatic angle, identifying conditions to develop strategies to consistently induce the appearance of false targets in the bistatic scene and an analysis on how to place the false targets in the same position in the different bistatic images.
