雷达抗压制干扰能力动态定量评估方法

A Method of Dynamic Evaluation of Radar Capability of Countering the Oppressive ECM

针对压制干扰条件下的雷达实际探测能力的动态评估问题,文中基于对雷达指向目标的天线增益G_T (θ)和干扰机指向雷达的天线增益G_j((?))的分段近似定量描述,推导出综合考虑G_j((?))、R_j随时间变化的雷达自卫距离一般表达式,提出了压制干扰条件下的雷达有效探测指数的概念和定量估算公式,并讨论了五种P_d要求时的雷达有效探测指数随(?)、R_j的变化规律。实例仿真表明,该评估方法的准确性和有效性均可满足雷达装备作战效能评估、雷达装备部署优化设计等实际应用需求。

For the dynamic evaluation of radar detection capability under the condition of oppressive jamming,based on the multipartite approximate fix-quantify description of radar-to-target antenna plusG_T(θ)and jammer-to-radar antenna plusG_j(φ),a general expression of radar self-defence distance which taking the time-variable G_j(φ),R_j into consideration is put out,an index of effective radar detection and its fix-quantify calculation formula are presented, the changing rules of radar effective detection index with 5 different P_d are discussed.Simulation shows that the veracity and efficiency of the method can apply to the campaign efficiency evaluation of radar equipments and optimal design of radar deployment.
