Description

technical field [0001] The invention relates to the technical field of radar, in particular to a Ku-band phased array water surface target detection system with adaptive beam stabilization. Background technique [0002] As an important radio navigation device, radar can detect the distance information and azimuth information of surface targets in real time; however, when water platforms such as wave gliders are navigating at sea, they will be affected by meteorological environments such as waves, sea winds, and tides. It causes the carrier itself to roll and pitch, which greatly reduces the radar's ability to detect targets and azimuth resolution, and even causes the radar system to fail to track targets. Therefore, under different sea conditions, it has been a hot topic of research to keep the radar detection beam stable in different ways, and to improve the azimuth resolution and detection stability of the radar in the case of small volume. [0003] At present, in order t...

Problems solved by technology

[0004] However, the disadvantage of this method is that it is necessary to add a stable platform to the carrier, and as the latitude of the stable attitude increases, the weight of the stable platform increases; as the weight of the stable load and the range of stable angles increase, the structure of the stable platform itself The size and power consumption increase; therefore, installing a stable platform on a small and medium-sized carrier is vulnerable to the constraints of space size, carrier load weight, and power consumption
