Height finder

Height finder

A height finder is a ground based aircraft altitude measuring device.

Technology

Early height finder implementations were optical devices and later migrated to radar devices. Devices combining both optics and radar were deployed by the United States Navy [cite web

Optical

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 gunscite web

Radar

A height finder is a type of 2-dimensional radar that measures altitude and direction of targets [cite web

Modern radar sets have 3-dimensional capability making height finder radars largely obsolete.fact|date=August 2007
