WebOverview NASA pioneered Navigation Doppler Lidar (NDL) for precision navigation and executing well-controlled landings on surfaces like the moon. The lidar sensor utilizes Frequency Modulated Continuous Wave (FMCW) technique to determine the distance to the target and the velocity between the sensor and target. WebFor time-of-flight LIDAR, one obviously requires a laser source emitting short pulses, often with pulse durations of the order of a few nanoseconds or sometimes <1 ns. The pulse energy must be high enough to provide sufficiently intense return signals; it may be limited by eye safety considerations (see below).
