一、前言八毫米CW超外差高频比相引信雷达(以下简称CWPCR)参考了百舌鸟导弹引信的设计思想,在体制和技术上对百舌鸟导弹引信进行了重大改进,其灵敏度比百舌鸟高20多分贝。采用锁相技术后,灵敏度还可以大大提高。对不同速度目标具有最佳引爆的预装角可调范围比百舌鸟大15°。接收机输出信噪比大于16db同时还成功地控制和利用漏功,解决了在超外差式体制中准确提取多卜勒信息和相位信息的难题。从而简化了整机系统,提高了可靠性。
I. INTRODUCTION The eight-millimeter CW superheterodyne high-frequency phase-matched fuze radar (hereinafter referred to as CWPCR) has made reference to the design concept of the hundred-tongue missile fuze and has made significant improvements in system and technology to the hundred-tongue missile fuze with a sensitivity of more than 100 High 20 decibels The use of phase-locked technology, the sensitivity can also be greatly improved. Adjustable range for pre-loaded angle with optimum detonation for different speed targets is 15 ° greater than Brachypodium. Receiver output signal to noise ratio greater than 16db also successfully control and use of leakage power to solve the problem of accurately extracting Doppler information and phase information in superheterodyne system. Thus simplifying the whole system and improving the reliability.
