宽带侦察灵敏度提升设计

Design for Improving The Sensitivity of Wideband Reconnaissance Equipment

随着电子战在现代战争中的地位越来越高,未来战场上电子战水平的高低一定程度上决定了局部战争的成败。目前电子战侦察设备面临新型低截获概率雷达的严重威胁:低截获概率雷达通过脉冲压缩等新型处理方式大大提高了检测信号的信噪比,从而降低了接收机的检测灵敏度,使得该类雷达可以在辐射信号功率极低的情况下探测目标。因此提高侦察设备灵敏度具有重要的意义。首先介绍了国内外侦察设备的灵敏度现状,分析了老式设备灵敏度的瓶颈,给出了提升该设备灵敏度的方案。文章最后给出了测试方案和测试结论,证明了方案的可行性。

With the electronic warfare’s status in the mordern war is more and more high,the level of electronic warfare(EW)in the future battlefield determines the success or failure of the local war to a certain extent.At present,the reconnaissance equipment of EW is faced with the serious threat of low probability of intercept(LPI)radar:by using the new processing methods such as pulse compression,etc.,LPI radars has greatly improved the signal to noise ratio(SNR)of the detection signals and reduces the detection sensitivity of receivers,which makes the targets with very low radiated power can be detected by using this kind of radars.So it is very important to improve the sensitivity of the reconnaissance equipment.At first,this paper introduces the present situation of the sensitivity for the reconnaissance equipment home and abroad,then analyzes the bottleneck of the sensitivity of old equipments,gives a scheme for improving the equipment sensitivity,finally gives the test scheme and conclusion,which proves the feasibility of the scheme.
