| 摘 要： | BOC信号是一种分离频谱的调制方式，与传统的导航扩频信号相比，具有更强的抗干扰能力和更高的测量精度。但BOC信号自相关函数具有多峰值的特点，如何从接收端找出最大峰值并正确恢复BOC信号是技术难点。本文给出了一种BOC信号的捕获方案和具体的实现算法。

| Abstract: | The BOC signal is a split-spectrum modulation signal which is very different from the traditional PSK navigation signals and has some more advantageous characteristics. Using BOC signal makes acquisition more challenging and tracking potentially ambiguous due to its multi-peak autocorrelation function. This paper uses an adaptive acquisition approach for BOC signal, which can keep a constant false alarm rate. |
