摘要
针对利用常规干扰手段对宽脉冲线性调频雷达干扰时假目标密集度难以提高的现实问题,提出了一种新的干扰样式产生技术,即将接收到的雷达信号样本存入数字射频存储器(DRFM)中,然后对DRFM中的样本延时读出,通过卷积运算后,生成射频干扰信号转发出去。从原理和工程上分别对该技术进行了分析与设计,并进行半实物仿真,验证了这一干扰产生技术的有效性。
Aiming at the fact that the false target density is difficult to be improved when using the conventional jamming means to jam linear frequency modulation radar signal with wide pulse width, this paper presents a new jamming mode generation technique, which stores the received radar signal sample into digital radio frequency memory （DRFM）, then reads the sample in DRFM with time delay,generates and transmits the radio frequency （RF） jamming signals through the innovative calculation. This paper analyzes and designs the technique from aspects of principle and engineering,and performs half-practicality simulation, the result validates the validity of the jam- ming generation technique.
