| Abstract: | Deep space communications have entered a new era of high speed transmission.Based on the deployment of large arrays of small antennae within radio astronomy community.Deep Space Array Network(DSAN) has become the final means for high speed transmission of deep space network. Based on the FX correlator,the architecture of frequency domain beamformer which has integrated array signal forming with correlate processing is presented.The method presented in this paper is to break up the signal into different freq... |
