微波辐射计特性指标测试系统

以微波辐射计特性指标的基本定义为依据，提出了微波辐射计特性指标的测试系统及测试方法．该系统通过Ａ／Ｄ转换器将数据直接送入计算机，对测试过程及测试数据进行自动处理，并直接输出最终结果．运行结果表明，这套测试系统能有效地进行微波辐射计特性指标（定标方程和灵敏度，线性度和动态范围，积分时间，稳定性）的测试，它节省人力、时间，具有较高的可靠性．

A Test System for Microwave Radiometer Performance

This paper presents a test system and a method for the test of performance of microwaveradiometers according to specified definitions of the performance. In the system, the test data are directly fed to a computer through an A/D converter and, after automatic processing, the final resultsare given directly from the computer output. The results show that the performance of microwave radiometers, such as the calibration equation and sensitivity, linearity and dynamic range, integrationacme and stability can be obtained by the test system proposed, which is highly efficient and reliable.
