Abstract:
(EN) A magnetic compensation method based on an aeromagnetic compensation correction model, the method comprising steps of: before an aeromagnetic flight, acquiring, by means of an aeromagnetic compensation error model, an upper error limit of magnetic noise caused by an environmental background field of a survey region and an aeromagnetic flight platform; determining, according to the upper error limit of the magnetic noise caused by the environmental background field and the aeromagnetic flight platform, whether conditions are suited to performance of an aeromagnetic survey flight, and if so, then performing a calibration flight to acquire a compensation coefficient; and performing an actual flight to acquire attitude data, combining the same with the compensation coefficient acquired from the calibration flight to calculate a solution for an interference magnetic field, and performing magnetic compensation.
(FR) L'invention concerne un procédé de compensation magnétique fondé sur un modèle de correction de compensation aéromagnétique, le procédé consistant : avant un vol aéromagnétique, à acquérir, au moyen d'un modèle d'erreur de compensation aéromagnétique, une limite d'erreur supérieure de bruit magnétique provoqué par un champ d'arrière-plan environnemental d'une zone d'étude et une plateforme de vol aéromagnétique ; à déterminer, en fonction de la limite d'erreur supérieure du bruit magnétique provoqué par le champ d'arrière-plan environnemental et la plateforme de vol aéromagnétique, si des conditions sont réunies pour la réalisation d'un vol d'étude aéromagnétique, et si tel est le cas, à exécuter un vol d'étalonnage afin d'acquérir un coefficient de compensation ; et à réaliser un vol réel afin d'acquérir des données d'attitude, à combiner ces dernières avec le coefficient de compensation acquis à partir du vol d'étalonnage afin de calculer une solution pour un champ magnétique d'interférence, et à réaliser une compensation magnétique.
(ZH) 一种基于航磁补偿误差模型的磁补偿方法,包括步骤:在航磁飞行之前,利用航磁补偿误差模型,获取勘探区域的环境背景场及航磁飞行平台二者引起的磁噪声的误差上限;根据环境背景场及航磁飞行平台二者引起的磁噪声的误差上限,判断是否适合进行航磁探测飞行,适合的话,进行标定飞行,获得补偿系数;以及进行实际飞行获得姿态项数据,结合标定飞行获得的补偿系数,求解出干扰磁场,并进行磁补偿。
