射频平面阵列目标位置控制系统的研究
Research on Target Position Control System Based on Radio Frequency Plane Array
摘要
Abstract
Radio frequency simulation technique based on antenna array has been considered to carry out the effectiveness evaluation test for large equipment under the complex electromagnetic environment.It is difficult to adapt this test for traditional spherical array system with single test center.So it is urgent to construct a new type of array system to complete the new experiment.Accordingly the target position control solution based on the radio frequency plane array is put forward.A plane array structure is designed and constructed.Then the array feeding system and software modules of the target position control system are discussed,while exact position control algorithm and rough position control principle are emphasiced.A four-element synthesis method has been proposed to complete the exact position control,and the angular glint equation for positions achieved by the four elements is derived.Furthermore,the synthetic angular position accuracy of radiation signal produced by the system is tested under the typical frequency band in the microwave anechoic chamber.The result shows that the angular position simulation accuracy of the plane array system under X band is up to 1 mrad,which can be used to the effectiveness evaluation for large equipment.关键词
