The AN/APS 94 Side Looking Airborne Radar or SLAR was developed by Motorola and used on the Army OV-1B/D, and UH-1, the Navy P-2, P-3, as well as the Airforce JSTARS, and other military aircraft. It is an X-band radar with an 18' externally mounted antenna. It aquires a 'slant range' image of the surrounding terrain in 2 strips on either side of the aircraft. Aerobureau developed a digital postprocessing system to provide false color, and moving target indications. Civilian uses of the AN/APS 94 have included charting the extent of flood waters, mapping, locating lost vessels, charting ice floes, locating archaeological sites, seaborne polution spill tracking, and a varity of other geophysical surveying chores.

An operator controls the radar from this crew station. Constant input from the navigation and flight data instruments provide the information needed to precisely locate features on the ground and allow the digital post processing computers to extract data from the radar images. The antenna hangs below the fuselage so it can 'see' on both sides of the aircraft.
