Performance evaluation of radar systems in noise jamming environments

摘要

Radar systems are widely used for military, transportation and scientific purposes. For radars, the ability of the device to mitigate the effects of noise and interference is of great importance because it will determine its performance. Radars may suffer from attacks aimed to hinder their performance, known as jamming attacks. In this context, noise jamming attacks are a very common type of attack, thus reducing their effect is fundamental. Due to this fact, simulation and analysis of radar performance in different scenarios could help decrease possible threats. For this reason, in this paper the performance of radars in noise jamming environments is evaluated. To achieve this, a radar system, jammer attacks and anti-jamming algorithm are modelled and evaluated through simulations. The models and algorithms developed in this work could aid in the process of performance test and analysis of radars and could be used as a design platform of radars and jammers to reduce developing and implementation time.
