1.英国GEC—马可尼防御系统公司已提高它的“教练”—A和“教练”—B舰用威胁告警/ESM系统的技术要求.“教练”—A覆盖2～18GHz,是一个扩大的晶体视频/数字瞬时测频装置,使用4信道比幅测向天线阵,其方位精度为10°,威胁显示在10.16cm黑白监视器屏面上(监视器设在驾驶台),响应时间1s.“教练”—B覆盖2～18GHz,具有威胁告警和远程监视双重能力,用8信道比幅测向阵列,其方位精度为5°.用图形和表格表示的威胁数据可显示在舰上多用途显控台上,或经由专用ESM站显示,该专用ESM站装有36cm彩色监视器、键盘和跟踪球.
1. British GEC-Marconi Defense Systems Inc. has stepped up its technical requirements for “Coach” -A and “Coach” -B ship threat alert / ESM system. “Coach” -A covers 2 ~ 18GHz and is an expansion Of the crystal video / digital instantaneous frequency measuring device, the use of 4-channel amplitude directional antenna array, the azimuth accuracy of 10 °, the threat is displayed on the 10.16cm black and white monitor screen (monitor is located in the bridge), the response time of 1s Coach B covers 2 to 18 GHz with dual capabilities of threat alerting and remote monitoring with 8-channel amplitude-oriented array with azimuth accuracy of 5 ° The threat data presented in graphical and tabular form can be displayed on shipboard Applications are on the console or via a dedicated ESM station with a 36cm color monitor, keyboard and trackball.
