| 摘 要： | 星载微波辐射计的天线提供的是宽带噪声功率信号。为了对微波辐射计进行星载条件下的仿真研究，本文采用伪随机信号来仿真微波辐射计的输入信号。所仿真的输入微波辐射计仿真模型与实际噪声信号输入到实际微波辐射计系统的对比结果表明了其良好的线性度，目标辐射信号的特征可用适当分布的随机噪声的数字特征表现，能用于进一步的仿真研究。 |

| Abstract: | The signal given by the antenna of spaceborne microwave radiometer is a wide band noise power signal. For the simulation study of microwave radiometer under spaceborne condition the input signal of microwave radiometer is simulated by artificial random signal. The comparison of the simulation input signal through the simulation model of microwave radiometer and actual noise signal through the actual system shows that the linearity of the simulation input signals is very well. The features of radiant objective signal can be shown by the numeral features of the suitably distributed stochastic number. So they may be suitable for simulation study. |
