【摘要】：研究了平面近场在中场测试距离情况下对方向图测试结果的影响。首先,采用理论分析与仿真方法,指出了扫描面积与方向图置信角度的关系为θ_(valid)=arctan(L-D/2d),通过实验验证了仿真结果。中场测试对方向图的影响是环境与动态范围,采用增加放大器及口径场回推截断环境的方式,可很好地改善测试结果,并通过实验验证了方法的正确性。
[Abstract]:The effect of the plane near field on the test results of the opposite direction diagram under the field test distance is studied. Firstly, the relationship between the scan area and the confidence angle of the pattern is pointed out by theoretical analysis and simulation, and the result of simulation is verified by experiments. The influence of the direction diagram of the field test is the environment and the dynamic range. By adding the amplifier and the truncation environment of the aperture field, the test results can be improved very well, and the correctness of the method is verified by experiments.
