一、引言微波暗室也称称“无回波暗室”(Anechoic Chamber),是一个以吸波材料铺设其内壁的建筑物,它能模拟自由空间进行多种试验,如可进行各种天线、天线罩的测试,各种飞行器的雷达反射截面特性(R C S)的测试以及电磁兼容(E M C)等方面的试验,因它不受外界电磁波的干扰与气候的影响,故具有完全、保密、方便等特点,是从事科学研究的一个重要实验手段。我所拥有一个24×8×8米的微波暗室,外壳带有屏蔽层。为了能够充分地发挥出暗室的特有的使用价值,需要对它的各种性能进行全面的鉴定测试。为此我
I. INTRODUCTION Anechoic Chamber is also known as Anechoic Chamber. It is a building whose inner wall is made of absorbing material. It can simulate free space for a variety of tests, such as various antennas, antennas Cover test, RCS test and electromagnetic compatibility (EMC) test of various aircraft. Because it is immune to external electromagnetic interference and climate, it has the characteristics of completeness, confidentiality and convenience , Is engaged in scientific research is an important experimental means. I have a 24 × 8 × 8 m microwave anechoic chamber with a shield. In order to be able to fully exploit the darkroom’s unique use value, its performance needs to be fully qualified test. For this I
