    摘要: A laser rangefinding system utilizes multiple pulse, multiple return, modal range processing for clutter rejection. A laser source (58) emits a series of laser beam pulses (60), and each reflected return from objects (54, 56) in a scene (52) for each of the pulses (60) is recorded. Each return signal above a predetermined threshold is added as a count to a count table within a selected bin representing the range of the return signal. After all of the analog return signals are recorded, the range bin with the most counts is selected as the range of a target (54).
