在导弹发射地点使用仪器的主要困难是地面回波,它妨碍了用普通雷达收集导弹刚发射时的详细的飞行信息。为了减轻这个问题,已设计成激光雷达系统,操作时使激光束精确地聚焦到远离喧噪的废气流的鼻锥上的一个点上。对于高性能导弹的自动跟踪及其位置和速度的实时显示,该系统的跟踪能力允许使 The main difficulty with the use of the instrument at the missile launch site was ground-based echoes, which prevented the use of normal radars to gather detailed flight information as soon as the missile was launched. To alleviate this problem, a lidar system has been designed that operates to precisely focus the laser beam at a point on the nose cone away from the noisy exhaust flow. For high-performance missile automatic tracking and its position and speed of real-time display, the system’s tracking capabilities allow
