摘　　要：基于多台海洋磁力仪、测深仪和GPS,研制了数据合成器、水下拖体、电源适配器、数据收录兼导航软件,最终构建了一种阵列式海洋磁力测量系统。该阵列式海洋磁力测量系统具备3个磁力仪通道,动态噪声≤0.3n T p-p,采样率为10Hz,水下部分总重量≤95kg,配迫降翼后入水深度可达22m。该阵列式磁力测量系统曾被应用于董家口港区某锚地的未爆炸物探测,最终确定了多个疑似物位置。Marine magnetic detection is wildly used in marine terrain survey and ocean engineering. At present,the single marine magnetometer is wildly used. A marine magnetometer array system has the advantages of high efficiency,high density in surveys,and is available as gradiometer and needs no diurnal correction. It ＇s very suitable for the detection of routings and small magnetic objects. Based on several marine magnetometers,depth meters and GPS,we designed the data synthesizer,power adapter,data acquisition and navigation softw are,assembled this marine magnetometer array system finally. The array system consists of three magnetometer channels. The dynamic noise ≤0. 3n Tp-p,the sample rate is up to 10 Hz,the underw ater weight is ≤95kg,and underw ater penetration can reach 22 m with diving wing. The marine magnetometer array system is applied to the underw ater UXO detection of boat basin in Dong Jia Kou port where several suspected objects was located.
