【摘要】 本文提出一种适用于高温环境的雷达散射截面积(RCS)相对标定测试方法,通过构建标准定标体电磁散射特性和温度之间的量化关系模型,避免了传统高温测试过程中标准定标体可能因高温导致的软化、变形或氧化等问题,从而确保了高温下RCS数据的准确获取。实验采用不锈钢(304)空心金属球作为定标体,在8 GHz频率下对GH3039高温合金板进行高温(800°C)RCS测试,结果显示测量均值误差≤1 dB。更多还原

【Abstract】 This paper proposes a radar scattering cross sectional area(RCS) relative calibration test method suitable for high-temperature environments.By constructing a quantitative relationship model between the electromagnetic scattering characteristics of the standard calibrator and the temperature,it avoids the problems of softening,deformation or oxidation that may be caused by high temperature in the traditional high-temperature test process of the standard calibrator,and thus ensures that the RCS data are accurately acquired at high temperatures.A stainless steel(304) hollow metal sphere was used as the calibrator for the high-temperature(800°C) RCS test of GH3039 high-temperature alloy plate at 8 GHz,and the results showed that the mean error of the measurement was ≤1 dB.更多还原
