Description

Technical Field

[0001] The utility model belongs to the field of airborne antenna equipment, in particular to an airborne antenna experimental device. Background Art

[0002] Synthetic aperture radar (SAR) is a high-resolution imaging radar that carries a phased array antenna on a satellite. The relative motion between the radar and the target can be used to synthesize a radar with a larger equivalent antenna aperture by using data processing methods to convert the smaller real antenna aperture into a larger equivalent antenna aperture. In order to fully verify its imaging performance, airborne experiments are often carried out before the phased array antenna is installed on the satellite. Airborne experiments can be carried out on large manned aircraft and small unmanned aircraft. Although manned aircraft have significant advantages such as high flight altitude and strong carrying capacity, there are a series of problems such as high rental cost, difficulty in modification, and long airspace application time when using manned aircraft. In recent years, with the widespread development of unmanned aircraft technology, the rental of unmanned aircraft is cheap and convenient, and the use of unmanned aircraft for airborne experiments is obviously a good alternative to manned aircraft. However, the carrying capacity of unmanned aircraft is small, and according to the actual load-bearing and speed, there will be a problem of the nose tilting downward at a certain angle during flight. In addition, due to the requirements of flight altitude and imaging mode, the tilt angle between the antenna and the ground also needs to be adjusted. It is particularly important to design an airborne experimental device with a small size, light weight, and manual compensation for the tilt angle of the unmanned aircraft and adjustment of the tilt angle between the antenna and the ground.
