摘　　要：舰载雷达侦察装备灵敏度、动态范围是其考核的重要指标,与装备战术使用息息相关。解析了动态范围、灵敏度的指标含义,建立与雷达侦察装备的战术映射公式,并通过单目标映射、多目标映射建立了舰载雷达侦察装备最小侦察距离与最大侦察距离的能量域模型,由实际灵敏度与灵敏度指标入手,建立了装备能量域与空间域的映射关系。仿真结果表明,实际灵敏度与灵敏度指标不同,对作战使用有一定影响,在面对高功率高威胁雷达时犹为明显,在作战使用中需重点关注。The sensitivity and dynamic range of shipborne radar reconnaissance equipment are important indexes for its assessment,which are closely related to the tactical use of the equipment. This paper analyzes the index meaning of sensitivity and dynamic range,establishes the tactical mapping formula with radar reconnaissance equipment and builds the minimum reconnaissance distance and maximum reconnaissance distance of shipborne radar reconnaissance equipment through single target mapping and multi-target mapping. The mapping relationship between equipment energy domain and space domain is established by the actual sensitivity and sensitivity index. The simulation results show that the difference between the actual sensitivity and the sensitivity index has a certain impact on the operational use,especially in the face of high power and high-power and high-threat radar.
