摘要
本文论述了一种采用脉冲调制恒流源开关实现噪声注入的零平衡辐射计的工作原理及其性能。实测表明,此种类型微波辐射计具有灵敏度高、稳定性好、动态范围宽以及输出线性好等特点。
This paper describes the design concepts and operation character- istics of a null-balancing type microwave radiometer which was developed by use of pulse modulating noise source directly to provide variable noise injecting. Practical applications have shown that this series of microwave radiometer has several attractive features that is high radiometrilc high precision.
