正在生产和开发中、采用相位比较技术和瞬时测频技术的被动定位系统可快速定位和识别在多路径和密集信号环境中的雷达发射机。这些系统的精度极高,完全能识别和定位敌方射频发射机。即使没有己方雷达照射,也能进行防御导弹的被动发射,因此,它的一个优点是能在给定环境中保持“寂静”,同时仍能监测和应付任何敌方射频威胁。 1 精确海上ESM Anaren公司的海上ESM接收机子系统包括普通Cutlass ESM组件的天线和接收机部分。雷卡防御系统公司将该系统与处理机、控制器和显示器组成一体。射频信号由一个32元锥形 In production and development, passive positioning systems that employ phase comparison techniques and instantaneous frequency measurement techniques can quickly locate and identify radar transmitters in multipath and dense signal environments. The precision of these systems is extremely high, fully capable of identifying and locating enemy RF transmitters. The passive launch of defensive missiles, even without their own radar, has the added benefit of being “quiet” in a given environment while still monitoring and responding to any enemy RF threats. 1 Accurate Offshore ESM Anaren’s offshore ESM receiver subsystem includes the antenna and receiver sections of a regular Cutlass ESM component. Reka Defense Systems combines the system with processors, controllers and displays. The RF signal consists of a 32-element cone
