noise-mudulation
根据干扰信号波形样式的不同,压制性干扰可分为噪声调幅干扰、噪声调频干扰、噪声调相干扰。就是用噪声或类似噪声的干扰信号遮盖或淹没有用信号,阻止雷达检测目标信息。它的基本原理是:任何一部雷达都有外部噪声和内部噪声,雷达对目标的检测是在这些噪声中进行的,其检测又是基于一定的概率准则的。一般来说,如果目标信号能量S与噪声能量N相比(信噪比S/N),超过检测门限D,则可以保证一定的虚警概率Pfa的条件下达到可检测目标回波所要求的检测概率Pd,简称为可发现目标,否则便称为不可发现目标。(Blanket Jamming can be divided into different styles according to the interference signal waveform, noise AM interference, noise FM jamming noise phase modulation interference. With noise or noise-like interference signal covered or submerged useful signal prevent radar detection target information from. Its basic principle is: any one radar has the external noise and the internal noise of the radar target detection in these noise detection is based on a certain probability criterion. Generally, compared to if the target signal energy S and noise energy N (signal-to-noise ratio S/N), more than the detection threshold D, you can guarantee reach target echo can be detected under the conditions of a certain false alarm probability Pfa requirements detection probability Pd, referred to can be found in the target, otherwise known as not finding the target.)
