摘要
双色技术是激光目标探测系统常用的提高目标探测和抗干扰能力的手段之一。针对空空导弹激光引信的使用要求和面临的主要问题,提出了双色激光共轴近场探测系统的设计方法,解决了共轴光学系统和双色发射、接收电路等关键技术,加工装配完成了探测系统样机,并进行了探测性能试验和抗干扰试验。试验表明,双色激光能有效识别云雾、烟雾等气溶胶类干扰。
Dual-wavelength technology is one of the most often used methods to improve the target detecting and anti-interfering capabilities of the laser target detecting devices （TDDs）. In order to satisfy the applying requirements and to solve the main problems of the laser proximity fuse on air-to-air missile, the design method of the dual-wavelength coaxal near-field laser detecting system is proposed, and the key technologies such as the coaxal optical system and the dual-wavelength emitting and receiving circuits are studied. Furthermore, the prototype system is fabricated and assembled, and the detecting performances experiment and anti-interference experiment are carried out. The experimental results show that the dual- wavelength lasers can identify the aerosols such as mist and smog.
