A new sighting telescope with an electromechanical hand wheel and a microprocessor for accurate ranging and automatic firing table set-up is proposed. Its function,concept and target ranging method based on an electromechanical hand wheel are introduced. The ranging error and the feasibility of this method were analyzed. The method of the elevation angle calculation and the mode of the firing table set-up are also discussed. The merits of traditional optical sighting telescopes and electro-optical sighting systems with laser range finders are retained in this design scheme. It integrates ranging,resolving and set-up functions in one unit,and can adopt several kinds of resolving and set-up modes for different situations. It is small,convenient,reliable and low cost.
