A new evaluation model of comprehensive radio frequency stealth performance of radar

Abstract

The detection capabilities of passive electronic warfare reconnaissance equipment have substantially increased during recent years. Correspondingly, the radar equipment is required to take various means to improve the radio frequency (RF) stealth performance to ensure the transmitted RF signal does not get intercepted. However, traditional evaluation methods on RF stealth performance cannot accurately evaluate the RF stealth capabilities of new system radar. In this study, a joint interception probability evaluation model on RF stealth performance was established, which divided the interception process into two parts: front interception and system interception. Various RF stealth means adopted by different radar equipment were taken into consideration to improve the applicability of this model. Simulation results show that this model is able to effectively characterize almost all the aspects of the RF stealth features and can serve as a good reference to evaluate RF radar stealth performance comprehensively.
