AI Technical Summary
Existing wind profiler radar systems are complex and costly, and beam quality bottlenecks are evident when miniaturizing antenna arrays. Traditional parabolic antennas require complex servo control systems.
The system uses a parabolic antenna combined with multiple electric actuators for elevation and azimuth angle control, eliminating the complex servo system of phased array and traditional parabolic antennas. Antenna pointing control is achieved by adjusting the extension and retraction length of the electric actuators.
It achieves a simple radar structure, is easy to manufacture and install, has low cost, is suitable for miniaturized radar, has low signal loss, and has stable and reliable detection performance.
