摘　　要：雷达辐射的功率会影响射频隐身性能,基于对射频隐身原理的分析,提出了目标跟踪状态下射频隐身功率实时控制的方法。实现了在射频隐身状态下,雷达跟踪单目标和多目标的辐射功率的实时控制。利用射频隐身性能指标和雷达临界截获模型,建立跟踪状态下雷达低截获模型。并以截获概率为优化目标,雷达最小接收功率为约束条件,得到了跟踪状态下单次辐射功率控制模型。提出基于目标跟踪状态下跟踪单目标和多目标的射频隐身功率控制方法。仿真实验与传统的功率最小法比较,得到该方法实现较低的雷达截获概率,证明了功率控制方法的合理性和有效性。Radar radiation will affect the RF power stealth performance ,based on the analysis ofRF stealth principle , a method for tracking the status of the target RF stealth power real-time controlis getten. Realize real-time control radiation power radar tracking single target and multiple targetsunder the cloak state radio . Using radio frequency radar stealth performance indicators and criticalinterception model established under the state radar tracking LPI model . And probability of interceptfor the optimization target ,the radar minimum received power for the academic conditions to obtainasingle radiation power control model tracking state . Target tracking based on single target and multi-target radio frequency stealth power control method is proposed . Compared with the traditional powerminimum method ,the method can realize the low probability of interception ,the rationality andeffectiveness of the power control method is proved.
