| 摘 要： | 为减小连续波、间断半连续波半主动雷达导引头制导系统中照射器和导引头固体本振的近载频噪声，采用倒置接收系统复现时廷极小的照射器调频噪声（相位噪声），直波锁相接收机本振信号与回波泄漏信号进行混频对消可明显降低中频相位噪声。分析结果表明，倒置接收可改善导引头泄漏下能见度（SFV）。

| Abstract: | To decrease near carrier frequency noise of illuminator and solid local-oscillator of seeker in the guidance system of CW and ICW radar,the mixture of real receiver local-oscillator signal and echo leaking signal was used to lessen the phase noise of intermediate frequency greatly by applying a inverted receiving system reappearing FM noise of the illuminator(phase noise) with very small time delay in this paper.The analysis results showed that inverted receiving could improve the leaking visibility of seeker. |
