Other AbstractThis paper is focused on the problem that the analog correlator unit of synthetic aperture radiometer is becoming too complex ,so that it has an inverse effect on the implementation of spaceborne synthetic aperture radiometer. There is a new digital correlator ,which uses the technology of digital receiver that has already been used in soft radio.Due to the fact that the digital correlators are realized with the help of analog2digital converter (ADC) chips and the FPGA technology ,the realized volume ,mass ,power consumption and complexity turn out to be greatly reduced compared with those of the analog correlators. Simulations show that the resolution of ADC has an influence on the synthesized antenna patterns ,but this can be neglected if more than 2 bits are used
