抗干扰性能是表征武器系统的必要指标,其重要性与日俱增。转发式 Doppler 干扰技术,具有适应的微波频带宽,干扰频率对准性好、功率利用率高、反应速度快、易于生产制造和成本低等特点。60年代以来,外军多广泛采用。针对制导系统、产生欺骗效果,针对引信系统、促使早炸。本文对通常采用的连续波行波管(TWT),进行锯齿型(Serrody)调相,以产生仿真 Doppler 频率的方法、理论和实验进行了系统分析的基础上,提出了一个鉴别真伪Doppler 信号的简易方法。当被干扰雷达接收到 Doppler 信号的同时,查询是否有伴随的尖脉冲信号出现,即可判断其真伪。附加一选频滤波器即可实现抗干扰。并附有简明示例。
Anti-jamming performance is a necessary indicator of weapon system, its importance is increasing. Forward Doppler interference technology, with adaptive microwave frequency bandwidth, good interference frequency alignment, high power utilization, fast response, easy to manufacture and low cost. Since the 1960s, the foreign military has adopted it extensively. For guidance system, resulting in deceptive effect, for fuze system, to promote early fry. In this paper, the commonly used continuous wave traveling wave tube (TWT) is subjected to Serrody phase modulation to generate the method of simulating Doppler frequency. Based on the theoretical analysis and experimental analysis, a new method to distinguish true and false Doppler signals Easy way. When the interfered radar receives the Doppler signal, inquiring whether there is an accompanying spike signal to judge its authenticity. Add a frequency-selective filter to achieve anti-interference. With a concise example
