一种新的量子遗传算法在阳山金矿GPS卫星信号去噪处理中的应用探讨

在GPS控制测量中，由于各种因素的综合干扰，造成GPS卫星接收机接收的卫星信号减弱，并伴随各种噪声。研究设计了一种新的量子遗传算法，根据数学形态结构元素参数特点初始化量子遗传种群，通过量子交叉、变异以及基于膨胀系数的量子旋转门实现种群的演化进程，进而对卫星信号进行去噪处理并降低基线残差来提高基线解算精度。以武警黄金第十二支队在甘肃阳山金矿采集的GPS数据为基础，采用3种方法对卫星信号进行去噪处理，通过对比发现新的遗传算法能将噪声信号的信噪比由-0.92 dB提高到5.11 dB。

Application of a New Quantum Genetic Algorithm on Denoising Processing of GPS Satellite Signal at the Yangshan Gold Deposit

In the process of GPS control survey，there were various factors of the comprehensive interference，which caused that the GPS satellite receiver received the abated signal，and together with all kinds of noise.In this study，we designed a new quantum genetic algorithm based on mathematical morphology characteristics of element parameters initialization quantum genetic populations.Through quantum crossover，mutation，and based on the expansion coefficient of quantum rotation gate realize the population evolution process，we dealed with the noise of the satellite signal，and lowed residual error of the baseline，therefore，calculating precision of baseline was improved.On the basic of data collected by GPS at the Yangshan gold mine in Gansu Province，and using three methods to deal with the noise of satellite signal，after comparation we found that the noise signal of signal-to-noise ratio was improved from -0.92 dB to 5.11 dB with the new genetic algorithm.
