激光雷达与微波雷达的比较在一定的工作条件下,激光跟踪器比普通雷达要好得多。特别是脉冲激光器的脉宽窄,峰值功率高,因而其测距精度和分辨率优于脉宽较宽的雷达系统。就角跟踪精度而言,小而轻的系统可以获得成形良好的窄激光光束角,而等效的窄波束雷达必须在很短的波长下工作,或采用大孔径天线。激光系统的另一个特征是不受地面杂波和多路效应的干扰,并能使激光系统以很低的仰角跟踪目标,没有雷达系统遇到的信号 Laser radar and microwave radar comparison Under certain working conditions, the laser tracker is much better than the normal radar. Especially pulse laser pulse width narrow, high peak power, so its ranging accuracy and resolution is better than the wide pulse width radar system. In terms of angular tracking accuracy, a small and light system yields a well-formed, narrow laser beam angle while an equivalent narrow-beam radar must operate at very short wavelengths or with a large aperture antenna. Another feature of the laser system is that it is immune to surface clutter and multipath effects and enables the laser system to track the target at very low elevation without the signals encountered by the radar system
