转台对天线阵列角模拟精度的影响
Effects of the Rotating Platform on AntennaArray Angle Simulation Precision
摘要
转台和天线阵列是射频仿真试验系统的两个主要组成部分,射频仿真试验系统的精度是以天线阵列角精度来表征的。由于转台误差以及转台中心与天线阵列球心不重合等原因,会影响天线阵列角模拟精度。针对转台的运动性能,结合天线阵列三元组工作原理,研究计算了转台静态误差和动态误差的数学模型,最后给出了转台对天线阵列角模拟精度影响的仿真结果。
Abstract
The rotating platform and the antennaarray are two main parts of RadioFrequency (RF) Simulation Test System.The error of RF Simulation Test System is represented by the angle simulation precision of the antennaarraywhich may be influenced by the error of the rotating platform and the incoincidence between the rotating platform center and the spherical center of the antennaarray.The mathematic models of static and dynamic error of the rotating platform are analyzed and calculated out based on the operational principle of the antennaarray and motion performance of the rotating platform.Finallythe simulation results about rotating platforms effects on the angle simulation precision of the antennaarray angle are presented.
