| Abstract: | The requirement of a receiver used in the synthetic aperture microwave radiometer is presented.Based on the re- quirement,a receiver used in the L-hand synthetic aperture microwave radiometer is designed.System simulation of the re- ceiver is carried out in the Advanced Design System(ADS).The result is given and the local oscillator influence to the re- ceiver is analyzed.The gain of the system is 129 dB.The noise coefficient is 1.8 dB. |
