Abstract深空通信已进入了高速率传输的时代,借助于射电天文中的小口径天线组阵思想,深空阵列网络因其优越的性价比,已成为深空网络高速数据传输的最终解决途径,基于FX型相关器,提出了一种集阵列信号合成、相关处理为一体的频域波束合成器架构和方法.该架构和方法具有很强的鲁棒性和灵活性,并可支持多任务探测.同时,介绍了分析一综合滤波、阵列信号相干合成和自适应可变分数时延等信号处理关键技术.
Other AbstractDeep 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 frequency channels and analyze each frequency channel separately to obtain phase and delay feedback information. The method would be a significant step forward in both performance and complexity, which has great flexibility and robustness, and can support multi-missions. Finally, the key techniques of analysis-synthesis filtering, sub-array signals coherent forming, and adaptive variable fraction delay are described.
