Abstract : A range finding device and method for determining the distance between a submerged submarine and a target above the surface having a first and second periscopes mounted on a submarine with a known separation. These periscopes are rotatable and extensible above the surface and can determine the bearing from each of the periscopes to the target. A computer receives the bearings from the first and second periscopes and uses the bearings with the known preset distance between the periscopes to calculate the distance between the submarine and the target.
