Antenna directional diagram test method and equipment, and storage medium

Abstract

An antenna directional diagram test method and equipment, an antenna and a storage medium, the method comprising: acquiring echo data generated by the antenna emitting electromagnetic waves to a target scene, the target scene comprising a rotating reflector device (S301); determining target echo data corresponding to the rotating reflector device according to the echo data (S302); and determininga directional diagram of the antenna according to the target echo data (S303). The method can reduce the dependence of the antenna directional diagram on the test environment and the research and development cost, and improve the test effect.

Description

technical field [0001] The present invention relates to the field of control technology, in particular to an antenna pattern test method, equipment and storage medium. Background technique [0002] The test of the antenna pattern depends on the echo of the test target, and the test target generally uses a stationary corner reflector with a fixed position, because the corner reflector is located at zero Doppler in the frequency domain, and ground clutter is also mainly located at Zero Doppler, so ground clutter will affect the test effect of the antenna pattern. The current common solution is to build a microwave anechoic chamber and use wave-absorbing materials to absorb ground clutter, but the construction cost of the microwave anechoic chamber is extremely high, requires more capital investment, and also requires more labor costs and construction costs, so it cannot meet the requirements. The needs of most researchers. [0003] Therefore, how to better test the antenna p...
