在低信噪比环境中及极远测距范围内获得高精度距离测量量是深空测距面临的挑战。再生测距系统通过在航天器中将测距码再生，可将下行链路信噪比提升约30 dB，从而解决低信噪比问题，但是已知测距码的无模糊测距距离难以满足未来深空测距需要。通过对复合函数与测距误差的关系进行系统分析，提出通过改变复合函数降低测距误差的方法，并用m序列及新复合函数设计新测距码。共设计8个新测距码，测距误差方差比已知测距码降低0.28~3.78 dB，无模糊测距距离从7.5×104 km提升至117×104~17 884×104 km，扩展了15~2 384倍。其中包含一种直流分量为0的完全均衡的测距码。仿真结果表明：新测距码能为未来深空通信及深空探测提供更远距离内更高精度的距离测量支撑。

The challenge of deep space ranging is to obtain high precision distance measurements over long two-way distance and at low signal-to-noise ratios. The regenerative ranging system improves the downlink signal-to-noise ratio by approximately 30 dB by regenerating the ranging code in the spacecraft. However， the known regenerative ranging codes fail to meet the essential unambiguous distance requirements for future deep space missions. Firstly， the relationship between the combining function and the ranging error is systematically analyzed， and the method for reducing the ranging error by changing the combining function is proposed. New ranging codes are designed with m sequence and the new combining functions. A total of 8 new ranging codes are proposed. The ranging error variance is reduced by 0.28–3.78 dB compared to the known ranging codes. The unambiguous ranging distance is increased from 75 000 kilometers to 1.17–178.84 million kilometers， expanding by 15–2 384 times. One of the new ranging codes is fully balanced with a DC component of 0. The simulation results demonstrate that the new ranging code can provide higher precision distance measurement support for future deep space communication and deep space exploration over longer distances.
