Height finder

From Wikipedia, the free encyclopedia

A height finder is a type of 2-dimensional radar that measures altitude and direction of targets, but not their distance from the radar.

Such systems often complement 2-dimensional radars which find distance and direction, thus using 2 2-dimensional systems to obtain a 3-dimensional aerial picture.

In WWII, a height finder was a stereoscopic optical device used to determine the altitude of an aircraft (actually the distance from the emplacement), used to direct anti-aircraft guns. Examples of American and Japanese versions exist, certainly a German and Russian version exist.
