本文叙述一种精确测量发射初始段轨迹的连续波光学雷达(OPDAR)。单台仪器通过安置在导弹上的后向反射器精密地测量导弹的斜距、方位角和俯仰角。测得的数据适用于实时计算轨迹和在飞行事后,由计算机处理出高精度的位置、速度和加速度信息。为论证系统现实性,设计了一些关键组件的实验室模型。模型包括轴角编码器、后向反射器和测距系统。为测量激光噪声的影响进行了试验。
This article describes a continuous wave optical radar (OPDAR) that accurately measures the initial trajectory of the launch. A single instrument accurately measures the missile’s slant range, azimuth and pitch using retroreflector mounted on a missile. The measured data is suitable for real-time trajectory calculation and after flight, the computer processes high-precision position, velocity and acceleration information. To demonstrate the system reality, some key components of the laboratory model were designed. Models include shaft encoders, retroreflectors and distance measuring systems. Experiments were conducted to measure the effect of laser noise.
