| 在评价射频仿真暗室性能的各项指标中以静区反射电平性能最为重要，实际应用中
以实测的结果作为评价暗室性能和仿真试验结果评定的依据。研究了针对某特殊静区位置
的某射频仿真暗室，阐述了采用自由空间驻波比法进行暗室静区反射电平测试方案，将测
试得到的数据与仿真结果进行了相应的比对，重点分析了射频仿真暗室静区性能测试数据与
仿真结果存在偏差的主要原因，并有针对性地提出了静区性能改善的几项可行措施，希望能
够为国内射频仿真系统设计、建设和改造提供一定的借鉴和帮助。 |

| Abstract: |
| Among the indexes evaluating the performance of RF simulation chamber the perfo
rmance of reflection level in quiet zone is the most importan
t.In practical application the measured results are the base for evaluating cha
mber per
formance and simulation test results. In this paper,according to the actual cond
ition of quiet areas for s
pecific location of the anechoic chamber,using freespace V
SWR method to test the reflection level in anechoic chamber quiet zone is descri
bed，test dat
a is compared with the simulation results with focus on the analysis of the
r
eason why there exists deviation between test data and simulation results, and
several measures to improve the performance of quiet zone are proposed
in hope of providing reference and help for domestic RF simulation system desig
n, construction and renovati
on. |
