摘要
缩比测试是在较低高度下对满足缩比条件的小目标进行测试,以等效在真实高度下对大目标进行测试的情况。文中针对毫米波辐射计的探测研究,讨论了其缩比测试的原理及条件,并在两种高度下进行了实际的毫米波辐射计缩比测试及相应真实高度下的塔载测试,结果对比表明了缩比测试的可信性。该方法简单易行,可节省大量经费。
In contractible-scaled measurement, the small model was measured at low altitude to equal the actual measurement of large target at high altitude. The paper discussed the principle and conditions of contractible-scaled measurement of MMW radiometer firstly. Then the contractible-scaled measurement and the corresponding actual measurement was done at two scales of height. The results were contrasted to prove the validity o the contracbile-scaled measurement. The method is simple, convenient and economical.
