Abstract
In order to solve the problem of multi-path effect suffered by radar in the process of outfield low-altitude measurement of targets,this paper proposes a method to suppress multipath effect by absorbing array element device.The process of electromagnetic wave emission and reception during radar operation is analyzed,and the absorption array element device with high absorption efficiency is introduced,and the device parameters are reasonably designed.Combined with the theoretical equation of flight target,the absorption array element layout model is established to form a continuous suppression area that can cover the whole trajectory of low-altitude flight target.The test shows that the method can improve the usage environment of the outfield measurement equipment and effectively suppress the multipath effect of the radar in static calibration and low-altitude dynamic target measurement.关键词
