1947年,一架误入东德的美军C-47运输机被苏军高炮击落。由于事发当天天降大雾,能见度很差,仅凭肉眼观测是很难把这架运输机击落的,所以美军怀疑苏联已经在东德部署了火控雷达。为了证实这一点,美军对2架B-17轰炸机进行了改装,安装了电子侦察接收测向设备,并将其派到C-47坠落的地区轮番侦察。果然,2架飞机在那里接收到了频率为570兆赫兹的雷达脉冲信号,并对信号源进行了定位。后经证实,苏联在该地部署了缴获的德制“维尔茨堡”雷达,这次侦察行动也成为了美军对苏电子侦察的第一个成功案例。如今,电子侦察手段已发展为专用电子侦察卫星、侦察机、侦察船、地面监测站和通用ESM设备纵横交织的立体网络。电子侦察到底能获得什么重要信息,又是怎样获得的呢,本文就带您一探究竟。
In 1947, a U.S. C-47 transport plane strayed into East Germany was shot down by Soviet artillery. Due to heavy fog and poor visibility on the day of the incident, it was very hard to shoot down this transport plane with naked eye observation. Therefore, the U.S. military suspects that the Soviet Union has already deployed a fire-control radar in East Germany. To confirm this, the U.S. military converted two B-17 bomber aircraft, installed electronic reconnaissance and receiving direction finding equipment, and dispatched them to the area where the C-47 crashed for reconnaissance. Sure enough, two aircraft received a radar pulse of 570 MHz there and positioned the signal source. After the Soviet Union confirmed that the seized German-made “Würzburg” radar was deployed there, this reconnaissance operation has also become the first successful case of US military reconnaissance of the Soviet Union. Today, electronic reconnaissance techniques have evolved into a three-dimensional network of specialized electronic reconnaissance satellites, reconnaissance aircraft, reconnaissance ships, ground monitoring stations and general purpose ESM equipment. What kind of important information can be obtained by electronic reconnaissance in the end, but also how to get it, this article will take you a closer look.
