1. A method for finding a range, comprising:

  • (a) receiving laser beams reflected from a target and input, and outputting a corresponding electrical signal;

    (b) converting the electrical signal into range-finding data;

    (c) sequentially storing the range-finding data;

    (d) adding the stored range-finding data and previously processed and stored accumulated data, and storing results as accumulated data;

    (e) detecting data exceeding a threshold value from among the accumulated data as target signals; and

    (f) reading a target range based on the detected target signals, wherein (a) through (d) are repeated N times, and the accumulated data in (e) are obtained by repeating (a) through (d) N times.
