Description

Technical Field

[0001] The utility model relates to the technical field of radar monitoring, in particular to a synthetic aperture radar monitoring field of view range adjustment device. Background Art

[0002] There are three types of synthetic aperture slope radars currently on the market: portable, fixed and semi-fixed. Portable synthetic aperture radars are generally used in temporary places such as emergency rescue; fixed synthetic aperture radars are mainly used for long-term monitoring and in places with a relatively solid foundation; semi-fixed synthetic aperture radars are generally used in places that need to be moved, and according to monitoring needs, the site must be changed frequently. Synthetic aperture radars are generally fixed on a track, which is fixed on the ground or a base. Due to the limitation of the radar monitoring opening angle, the radar can only change the monitoring area by re-setting the track. For complex on-site monitoring environments, it is sometimes difficult to move the synthetic aperture radar monitoring equipment by manpower for fixed and semi-fixed synthetic aperture radars, and it takes time to use mechanical equipment. Sometimes the on-site space is not suitable for equipment-assisted movement, so it is necessary to design a device that can assist the synthetic aperture radar and the track to conveniently change the monitoring field of view.
