Radar reliability modeling approach in the repressive electromagnetic environment

The ability of radars to detect targets is affected by the electromagnetic interference. Aiming at the problem of estimating radar reliability under a repressive electromagnetic environment, this study analyzed the influences of suppressive jamming on the maximum detection range from the perspective of energy domain, then the quantitative method of radar reliability under electromagnetic interference was proposed. With the help of the Monte-Carlo technology, the simulation of jamming and working signals were carried out, then the maximum detection range was estimated, and finally, the degradation process of detection range of the radar among the changing electromagnetic interference was modeled based on the Normal degeneration distribution. It is helpful to predict the probability of radar to complete the specified task in the electromagnetic environment when the performance threshold is determined, which is beneficial to equipment configuration and task arrangement in actual scenes.
