Abstract The extinction ratio test of analogue ranging is adopted directly to check the sensitivity of pulsed laser range finders, then the influence of weather and the limitation of terrain in long-distance ranging can be elinminated effectively. By analyzing the test data obtained and comparing them with the range measuring ability, it shows that this check method is effective.
