摘要

摘要: 航空磁法勘探是一種高效、便捷的地球物理勘探方法。使用多個(gè)光泵磁力儀實(shí)現(xiàn)全軸梯度測量是航空磁法勘探中的一種重要手段。該文針對無人機(jī)飛行平臺設(shè)計(jì)了一種航磁全軸總場梯度測量系統(tǒng)，并提出使用前饋網(wǎng)絡(luò)的方法來實(shí)現(xiàn)航磁數(shù)據(jù)的補(bǔ)償。系統(tǒng)通過4個(gè)光泵磁力儀獲得全軸總場梯度數(shù)據(jù)，經(jīng)過前饋網(wǎng)絡(luò)實(shí)現(xiàn)數(shù)據(jù)補(bǔ)償后，全軸總場梯度數(shù)據(jù)補(bǔ)償質(zhì)量的提升比分別為15.2, 4.7和5.9，數(shù)據(jù)峰值信噪比的提升分別為17.1 dB, 6.5 dB和6.5 dB，交叉標(biāo)定系數(shù)表明前饋網(wǎng)絡(luò)具有很好的泛化性能。實(shí)驗(yàn)結(jié)果驗(yàn)證了該文采用的全軸梯度系統(tǒng)和數(shù)據(jù)補(bǔ)償方法的正確性和有效性，能夠有效地應(yīng)用于高精度航磁勘探領(lǐng)域。

Abstract: Aeromagnetic prospecting is an important method in geophysical prospecting for its high-efficiency and convenience. In the paper, a new kind of the three axis gradient system based on the unmanned helicopter is designed and an aeromagnetic compensation method based on the neural network is proposed. The system is equipped with four Optically Pumped Magnetometers (OPMs), from which the three axis gradient data can be achieved. In aeromagnetic compensation, the feedforward network is used. The Improvement Ratio (IR) of the three axis gradient data is 15.2, 4.7 and 5.9, respectively. The Peak Signal to Noise Ratio (PSNR) of the three axis gradient data is improved by 17.1 dB, 6.5 dB and 6.5 dB, respectively. Through the result of the Cross Calibration Index (CCI), the generalization ability of the method is good. The three axis gradient system and the aeromagnetic compensation are proven valid in aeromagnetic prospecting by an experiment.
