Description

Technical Field

[0001] The present application relates to the field of radar equipment, and in particular to a vehicle-mounted semi-rigid lifting and searching integrated radar antenna pedestal. Background Art

[0002] The antenna mount is the main component of the radar and is the support and orientation device of the radar antenna. Through the control system, the radar antenna can move according to a predetermined rule and can accurately output and feedback azimuth and pitch position information through the angle sensor.

[0003] At present, the radars used on semi-rigid lifting towers over 20 meters on vehicles are mainly search radars, and their antenna bases only need to realize continuous rotation in azimuth. The principle is that the motor drives the reducer to rotate, and the reducer drives the rotating support mechanism to rotate, thereby driving the radar antenna to rotate. However, due to the existence of a certain amount of tooth gap in the reducer, it can only meet the working conditions of the search radar gradually accelerating from static to a predetermined speed and continuously rotating at a uniform speed in one direction. It cannot meet the working conditions of the search and tracking integrated radars of the same power level to quickly adjust the side at a large angle and respond at a high speed when searching and tracking on semi-rigid lifting towers over 20 meters; the existing search radars on semi-rigid lifting towers over 20 meters on vehicles use natural wind heat dissipation, and the antenna base does not have a coolant transmission system used for high-power antenna liquid cooling; for most existing radars, the cables from the antenna base to the antenna are mostly exposed to the outside of the equipment, and the cable sheath is prone to rapid aging in environments such as high salt fog and strong ultraviolet rays.
