The results indicate that spread spectrum angle tracking system may obtain the same precision as mono pulse beacon tracking system;

结果表明：扩频角跟踪精度可达到单脉冲信标跟踪的精度；

The beacon signal is the reunite signal of linear FM signal and pulse code signal, and the pulse code signal is used as a token of emit signal.

信标信号为线性调频信号和脉冲编码信号的复合信号，其中脉冲编码信号用来表征发射信号序号。
