摘要
提出了合成孔径辐射计对接收链路的技术要求,并在此基础上设计了工作于L波段的合成孔径辐射计的接收链路。通过ADS(Advanced Design System)软件对该接收链路进行了系统级仿真,仿真结果表明,系统增益为129 dB,噪声系数约为1．8 dB,满足了设计目标对系统增益和噪声系数的要求。
The requirement of a receiver used in the synthetic aperture microwave radiometer is presented. Based on the requirement, a receiver used in the L-band synthetic aperture microwave radiometer is designed. System simulation of the receiver is carried out in the Advanced Design System （ADS）. The result is given and the local oscillator influence to the receiver is analyzed. The gain of the system is 129 dB. The noise coefficient is 1.8 dB.
