synthetic aperture radar; SAR :[A] synthetic aperture radar(SAR) is a side-looking imaging radar usually operating on either an aircraft or a spacecraft. The radar transmits a series of short, coherent pulses to the ground producing a footprint whose size is inversely proportional to the antenna size, its aperture. Because the antenna size is generally small, the footprint is large and any particular target is illuminated by several hundred radar pulses. Intensive signal processing involving the detection of small Doppler shifts in the reflected signals from targets to the moving radar produces a high resolution image that is equivalent to one that would have been collected by a radar with a much larger aperture.  4, record 1, English, - C%2Dband%20synthetic%20aperture%20radar

Satcom on-the-move(SOTM), or satellite communications on-the-move, is a phrase used in the context of mobile satellite technology, specifically relating to military ground vehicles. The basic principle behind satcom on-the-move is that a vehicle equipped with a satellite antenna is able to establish communication with a satellite and maintain that communication while the vehicle is moving.  3, record 2, English, - satellite%20communications%20on%2Dthe%2Dmove

MDV determines whether the majority of military traffic, which often moves very slowly, will be visible. To capture the majority of this traffic, a radar must have the ability to detect the lowest possible radial velocity. As a target's radial velocity approaches zero, the target will fall into the clutter or "blind zone. "The clutter spread is a function of a radar's antenna real bandwidth. When a target is in clutter, traditional MTI [moving target indicator] radars can either detect the target or locate it, but not both.  1, record 4, English, - minimum%20detectable%20velocity

Compared to real aperture radar, Synthetic Aperture Radar(SAR) synthetically increases the antenna's size or aperture to increase the azimuth resolution though the same pulse compression technique as adopted for range direction. Synthetic aperture processing is a complicated data processing of received signals and phases from moving targets with a small antenna, the effect of which is to should be theoretically convert to the effect of a large antenna, that is a synthetic aperture length...
