随着隐身技术的迅速发展,隐身兵器层出不穷,战场上的目标越来越难以被探测到。为了对付未来先进的低可观测性威胁目标,提高雷达的灵敏度至关重要。什么是高灵敏度雷达?顾名思义,高灵敏度雷达就是灵敏度较高的雷达,一般说来,能探测到隐身目标的雷达都可称为高灵敏度雷达。这些雷达利用目标信号特征或采用特殊技术(如较低工作频率、宽频带、多频谱、双极化、多基地、灵活扫描、多普勒效应等)及其他一些先进方法来捕捉微弱的目标信号。它们是隐身目标的克星,也是提高武器系统性能的重要电子设备。
With the rapid development of stealth technology, stealth weapons emerge in an endless stream, the battlefield goal is more and more difficult to be detected. In order to cope with the future of advanced low observability threats, increasing the sensitivity of the radar is crucial. What is the high sensitivity of the radar? As the name suggests, the high sensitivity of the radar is a high sensitivity radar, in general, to detect the stealth target of the radar can be called high sensitivity radar. These radars exploit the characteristics of the target signal or use special techniques such as lower operating frequency, wide band, multi-spectrum, dual polarization, multi-base, flexible scanning, Doppler, etc. and other advanced methods to capture weak target signals . They are the nemesis of stealth targets and are also important electronic devices that enhance the performance of weapon systems.
