Additional equipment includes an autopilot, communication and satcom radios, APN-241 precision ground mapping radar
integration, navigation sensors and surveillance systems including a Traffic Collision Avoidance System (TCAS), Terrain Awareness and Warning System (TAWS) and digital map.
The GR4 can operate in all weather conditions, using Terrain Following Radar (TFR) and Ground Mapping Radar
(GMR) to guide the aircraft and identify the target.
The simulator, like the real aircraft, has terrain following/terrain avoidance and ground mapping radar
Air Force combat controllers as a navigational aid to conduct precise air drops without the use of other external aids, such as global positioning systems (GPS) or ground mapping radar
They decided that this requirement could be met with the use of a variation of the ground mapping radar
using a synthetic aperture antenna, especially because the vehicles of interest moved at a small enough relative velocity to satisfy the phase coherency requirement.
Named radar potentials and limitations, it discusses space applications, radar used in navigation, with a look at the Navstar Global Positioning System (GPS), radar signatures, mapping radars
and medical applications.
