摘　　要：本文提出一种二阶类BPSK方法,该方法兼顾了运算量和灵敏度,有效消除了BOC调制信号的模糊度,使得接收机能够准确捕获卫星导航新体制信号。经过验证,该方法可以提高信噪比,实现BOC调制信号的高灵敏度捕获。In the paper,a second-order BPSK-like method is proposed,which takes into account both computation and sensitivity,effectively eliminates the ambiguity of BOC modulated signals,and enables the receiver to accurately acquire the signals of the new satellite navigation system.It is proved that this method can improve the signal-to-noise ratio and realize the high sensitivity acquisition of BOC modulated signals.
