摘　　要：传统的无人机测控信号容易被干扰和截获。在现有无人机测控系统的基础上,给出了一种无人机微弱扩频信号的单通道单脉冲跟踪系统的实现方法,同时突破了扩频信号并行快捕和误差电压的高精度相关解调等难题。该方法可以充分利用现有测控信道而无需额外增加设备量,具有跟踪系统灵敏度高、跟踪精度高、算法简单和设备简单等特点,特别适合于对无人机的隐蔽高精度测角跟踪。The conventional UAV TTC signals can be easily disturbed and captured. Based on UAV TTC system,this paper puts forward an implement method of single channel and single pulse tracking system for UAV feeble spread spectrum signal. At the same time,the difficulties such as parallel and fast acquisition of spread spectrum signal and high-precision correlation demodulation of error voltage are also broken through. This method can fully use the existing TTC channel without adding equipment,and it has such characteristics as high sensitivity,high tracking accuracy,simple algorithm,simple equipment,etc.,which is very suitable for high-precision angle measuring and tracking of UAV.
