SYSTEM AND METHOD FOR A RANGEFINDING INSTRUMENT INCORPORATING PULSE AND CONTINUOUS WAVE SIGNAL GENERATING AND PROCESSING TECHNIQUES FOR INCREASED DISTANCE MEASUREMENT ACCURACY

摘要

A system and method for a rangefinding instrument incorporating pulse and continuous wave signal generating and processing techniques for increased distance measurement accuracy. The use of the former technique effectively solves the ambiguity issues inherent in the latter while allowing for relatively simple circuit implementations. Thus, a potentially more accurate phase-based distance measurement technique can be utilized which is also completely independent of the maximum range to the target.
