提出了一种基于混沌同步的噪声鲁棒测距方法。该方法在雷达发射信号中叠加一个参考正弦信号，并经过混沌同步方法得到带有距离信息的恢复正弦信号，通过比较参考正弦信号和恢复正弦信号的相位差得到目标的距离。该方法和已有方法相比，具有一定的噪声鲁棒性，在噪声环境中测距精度得到提高。最后，仿真实验验证了所提出方法的有效性。

A noise robust method of measuring target distance through chaotic synchronization is proposed. In the method, a reference sinusoidal signal is superimposed to the radar transmitted signal. The recovered sinusoidal signal which contains the range information is obtained through chaotic synchronization method. The phase error of the reference sinusoidal signal and the recovered sinusoidal signal allows computation of the target distance. Unlike existing methods, the proposed method is more robust to noise. It has better ranging precision than that of existing methods. Finally, the proposed method is illustrated by numerical simulations to show its effectiveness on target distance measurement.
