摘要
采用提高漫反射信号强度方式来达到反隐形的雷达,是不可能从根本上实现反隐形的。提出了一种新的雷达反隐身技术,利用直边衍射来测量跟踪隐形飞行物体。利用直边衍射现象,当激光对隐形飞行物扫描时,不但可以模拟出隐形飞行物体所在的位置及飞行速度,还可以得到其大小和形状,能够对隐形飞行物体实现全场跟踪测量。利用直边衍射原理制作的雷达还具备数据加密功能。
At present,the purpose of anti-stealth has been achieved by improving diffuse reflectance signal strength for the most advanced anti-stealth radar,while it is impossible to achieve the fundamental anti-stealth by this method.So,a new radar anti-stealth technology is proposed and by means of straight edge diffraction it can be realized in measuring and tracking stealth flying objects.When scanning the stealth flying object with laser,not only the position and the flying speed of the stealth flying object can be simulated,but also the shape and size can be obtained.Thus,it can be realized in full tracking the stealth flying objects.In addition,the radar of using the principle of straight-edge diffraction has the functions of data encryption.
