SLAR can be fitted with a standard antenna (real aperture radar) or an antenna using synthetic aperture.
SAR is typically mounted on a moving platform, such as an aircraft or spacecraft, and has its origins in an advanced form of side looking airborne radar (SLAR).

Imaging radar

List of McDonnell Douglas F-4 Phantom II variants

F-4ERF-4CRF-4E
Tactical reconnaissance version of F-4B for United States Marine Corps, nose stretched 4 ft 9 in (1.4 m), smaller AN/APQ-99 radar. Three camera bays typically carried KS-87 forward oblique/vertical camera on Station 1, KA-87 low-altitude camera on Station 2, and KA-55A or KA-91 high-altitude panoramic camera on Station 3. Also carried AN/APQ-102 reconnaissance SLAR, AN/AAD-4 infrared reconnaissance system, and ALQ-126 ECM suite. The KS-72 or KS-85 cameras were on rotating mounts and could be aimed in flight which improved upon the earlier RF-4C which could only be aligned on the ground. In 1975, modernized under Project SURE (Sensor Update and Refurbishment Effort); 46 built. Retired in 1990. 4 lost in Vietnam. First flown 12 March 1965.

The availability of compact fast computers and high-capacity storage, combined with the availability of global digital elevation maps, has mitigated this problem, as TERCOM data is no longer limited to small patches, and the availability of side-looking radar allows much larger areas of landscape contour data to be acquired for comparison with the stored contour data.
