| 摘 要： | 提出了一种采用超宽带（UWB）高斯脉冲的测距系统,利用搜索者优化算法（SOA）搜索本地信号和接收信号之间相关的峰值,计算检测距离。分析了给定信噪比下接收机的相关结果、采用SOA的搜索过程以及搜索结果的概率分布。同时,在各信噪比下,与现有的步进相关法及门限判别法进行比较,仿真结果表明,信噪比在15 dB以上的系统测距测量误差达到3 cm,其性能优于门限判别法,而与步进相关检测法相当,但运算量较之减少84%左右。因此,该系统在高精度测距中极具实用价值。

| Abstract: | A Ultra-wideband(UWB) Gauss pulse ranging system based on Seek Optimization Algorithm(SOA) is proposed in this paper.SOA is used to seek the maximum correlation value of reflected signal,and then the detecting distance is calculated.The correlation value of receiver,search process of SOA and probability distribution of searching solutions are studied analyzed under given signal-to-noise ratio(SNR).Moreover,the system performance based on SOA is compared with those based on traditional method,Step Correlatin... |
