本文首先讨论了用快速自动增益控制实现双通道相除的音频调制假单脉冲雷达的抗调幅干扰问题。指出了当仅从抑止干扰这一观点出发,相除法对双通道幅相一致性无特殊要求。仅为了避免跟踪灵敏度的下降及方位、仰角二路误差信号的窜扰才对双通道高频支路有幅相一致性的要求。指出了当自动增益控制特性不是理想的y=x~(-1)时对干扰抑制性能的影响,并提出加校正函数以得到y=x~(-1)的理想特性。指出了由于相除是非线性
In this paper, we first discuss the anti-amplitude modulation interference problem of the audio modulated pseudo-monopulse radar with fast AGC. It is pointed out that there is no special requirement for the consistency of two-channel amplitude and phase when divided only from the viewpoint of suppressing interference. Only in order to avoid the decline in tracking sensitivity and azimuth, elevation error signal channeling only on the two-channel high-frequency branch has amplitude consistency requirements. It is pointed out that when the AGC is not ideal, the influence of the disturbance rejection is y = x ~ (-1), and the ideal function of y = x ~ (-1) is proposed by adding the correction function. Pointed out that due to the division is nonlinear
