摘要/Abstract

摘要：

提出一种针对动目标检测和成像雷达的正弦调频干扰产生模型，将接收到的雷达发射信号进行正弦波频率调制，再与假的动目标模板信号进行卷积后转发．假目标回波附加的正弦频率调制使得两个通道间信号的差异增大，相关性降低．当动目标回波功率与干扰功率比在区间［-16dB，-12dB］时，检测到的动目标方位向坐标和距离维速度估计出现较大误差，形成欺骗干扰．当动目标回波功率与干扰功率比小于-16dB时，大功率干扰信号的存在抬高了恒虚警检测门限，降低了检测概率，出现遮盖性干扰．仿真试验证明该方法干扰效果明显，且简单易实现．

Abstract:

A novel model to produce sinusoidal weighted frequency modulated jamming is put forward. And it is used to jam moving target detection and imaging. In the model, the radar transmitting signal frequency is modulated by the sinusoidal frequency. It is then convoluted with the false moving model signal and retransmitted. The jamming signal frequency is modulated by the sinusoidal frequency, so the signal difference between dual channels increases and there is less correlation. When the power ratio of the moving target echo to the jamming signal is between -16dB and -12dB, big errors occur in velocity and cross-range coordinate. Deception jamming can be obtained. When the power ratio between moving target echo and jamming signal is less than -16dB the detection threshold grows under the influence of the jamming signals of great power. And detection probability falls rapidly. By simulation the method has a good effect on jamming moving target detection and is realized easily.

Key words: electronic countermeasure, sinusoidal weighted frequency modulation jamming, moving target detection, displaced phase center antenna(DPCA), detection probability
