Frequency Modulated Continuous Wave laser and radio compound detecting technology

调频连续波(FMCW)激光引信具有定距精确度高,抗电磁干扰能力强等优点,但激光探测器易受云层、烟雾和雨雪的干扰,影响引信对目标识别。为此提出了一种FMCW激光与无线电复合探测技术,可有效地解决激光探测技术抗云层、烟雾、雨雪干扰的问题。在分析FMCW激光探测技术与FMCW无线电探测技术的工作原理基础上,给出了激光无线电复合探测方案,并验证了系统的可行性。

Although Frequency Modulated Continuous Wave(FMCW) laser fuze has the advantages of high ranging precision and strong electromagnetic anti-interference capability etc., laser detectors are susceptible to the clouds, smoke, rain and snow, which will influence the target recognition. An FMCW laser and radio compound detecting technology is presented, which can effectively help the laser detecting system to avoid from those interference. Based on the analysis of the working principles of FMCW laser detecting technique and FMCW radio detecting technology, a laser and radio compound detecting scheme is put forward, and the feasibility of the system is verified.
