毫米波辐射计的缩比测试

Contractible-scaled Detection of the Millimeter Wave Radiometer

采用缩比方法测试毫米波辐射计目标,较之传统的机载或塔载的方法可以节约大量经费。该方法是在较低的高度上测量满足缩比条件的较小目标,以等效在实际使用高度上测量真实大目标的结果。文章讨论了测试的远场条件,并对一个具体的缩比测试实验的结果进行分析,结果表明:该方法简便易行,数据可信。

Contractible-scaled detection is more economical than traditional machine-carried or towercarried method in millimeter wave radiometer target detection. This method tests the contractible-scaled model at contractible height to equivalent the actual outcomes. The paper discusses the far-field condition and analyzes the outcomes of a contractible-scaled test. The result shows that this method is simple, convenient and credible.
