Distance measuring equipment. In aviation, distance measuring equipment (DME) is a radio navigation technology that measures the slant range (distance) between an aircraft and a ground station by timing the propagation delay of radio signals in the frequency band between 960 and 1215 megahertz (MHz). Line-of-visibility between the aircraft and ...
An example of slant range is the distance to an aircraft flying at high altitude with respect to that of the radar antenna. The slant range (1) is the hypotenuse of the triangle represented by the altitude of the aircraft and the distance between the radar antenna and the aircraft's ground track (point (3) on the earth directly below the aircraft).
1 Battery. A battery [220] of QW-3 missile equipped with automatic launcher mounted on Shaanxi truck, 57 mm AA autocannon, SR-74 searching radar, and fire control command vehicle as part of CPMIEC TD2000B missile–gun integrated air defense system have been acquired. [221][222] Anti-aircraft gun.
High Resolution Wide Swath (HRWS) imaging is an important branch in synthetic aperture radar (SAR) imaging, a remote sensing technique capable of providing high resolution images independent of weather conditions and sunlight illumination. This makes SAR very attractive for the systematic observation of dynamic processes on the Earth's surface ...
The R-Han 122 was made by PT Dirgantara Indonesia (PT DI or IAe), Ministry of Research and Technology, Ministry of Defence, PT Dahana, and Pindad and in conjunction with the Indonesian Army. [5] It started in 2007 when the Ministry of Research and Technology formed the D-230 Team to develop a 122 mm diameter rocket with a range of 20 km (12 mi).
Distance measuring equipment – (DME), is a radio navigation technology that measures the slant range (distance) between an aircraft and a ground station by timing the propagation delay of radio signals in the frequency band between 960 and 1215 megahertz (MHz). Line-of-visibility between the aircraft and ground station is required.
The TKR's Ground, Air and Naval Forces, later the Indonesian Army, Air Force, and Navy, used these ranks with different insignias for Navy officers following Japanese and Dutch precedence. (The same Army ranks were also used by the nascent Indonesian Marine Corps which was established at the same time.)
To preserve return-signal strength, Quill's range from its target areas had been minimized by using an unusually steep depression angle. The resulting images, therefore, had slant-range scales that were much foreshortened versions of the ground-range (mapping) scale of level terrain. While slant-range images provide a realistic perspective of ...
