摘要
综述深空测控系统研制中的主要技术难点,包括:巨型天线及其组阵技术、极低噪声放大和低噪声天线技术、极限纠错编码技术、高精度干涉仪技术、毫米波和光波技术、超高稳定原子钟、高精度测距和测速、数字化小型应答机技术等。
Main technical chanllenges in deep space TT＆C system development are reviewed, including large antenna and antenna array, very low noise amplifier and low noise antenna, limit error correction and coding, intefferemeter with high accuracy, milimeter wave and optical wave technologies, atomic clock with super high stability, highly accurate range and range rate measurement, digital and small transponder etc.. Most of them are not only the most advanced TT＆C technologies, but also the most advanced information technologies.
