摘要
针对扩展频谱通信应用于空空导弹数据链时,如何实现在高动态猝发条件下扩频信号和载波的快速同步提出了一种解决方案,并对其关键技术进行了分析,经过测试,本方案可以较好地实现在低信噪比、大多普勒频移下信号的快速、准确的捕获和同步。
Aiming at the problem of spread spectrum technology used in data link of airborne missile, fast acquire high dynamic DSSS Receiver in burst mode is a key technology. A fast acquisition method is proposed, the design and implementation are introduced in detail. Engineering verification shows that it can be used to fast acquiring in low SNR and high dynamic situation.
