摘要
In this paper, 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 generated by the master chaotic system, and the radar received signal forces the slave chaotic system to generate the chaotic signal embedded in it, which can recover the sinusoidal signal by chaotic synchronization. The phase error of the reference sinusoidal signal and the recovered sinusoidal signal allows computation of the flight time of the transmitted signal. Thus, the distance of the radar from the target can be obtained. Unlike the existing methods, the proposed method is more robust to noise. The noise robust feature make the proposed method has more application potential than that of the existing methods. Finally, the proposed method is illustrated by numerical simulations to show its effectiveness on target distance measurement.
