Abstract

The invention discloses an antenna far field test system and method based on weather radar base data, and relates to the technical field of weather radar test. The transmitting antenna is mounted on the first antenna turntable and rotates along azimuth, pitching and polarization axes; an antenna to be tested and a standard horn antenna are installed on a second antenna rotary table through a radar receiver, the aperture faces of the antenna to be tested and the standard horn antenna form an included angle of 180 degrees, mechanical axes are coaxial, and the antenna to be tested and the standard horn antenna rotate along azimuth and pitch axes. The data processing device is connected with the radar receiver. The testing process is simplified, and the equipment cost and the maintenance cost are remarkably reduced. The test time is shortened, and the test precision of gain, beam width, sidelobe level and the like of the to-be-tested antenna is improved. The whole system has wider adaptability in practical application and is not limited by specific climate conditions. The test process is accelerated, and errors caused by human factors are reduced. The method has the advantages of simplicity in operation, high automation degree, high adaptability and the like, and the measurement precision and the test efficiency of antenna performance parameters are remarkably improved.
