| Abstract: | Through the improvement of CH-3 UAV aeromagnetic survey system of measurement and control software and hardware,differential GPS positioning data synchronization,system adaptability modification,and horizontal transverse gradient measurement,the authors carried out 1∶25000 large scale aeromagnetic survey test in Rudong coastal tidal flats area in Jiangsu Province,and verified the high precision measurement and control so as to improve the system stability and other key performance.Good application results were achieved in concealed rock mass,and fault structure and magnetic interface distribution were inferred,which shows that the method has broad application prospects in providing effective basic geological and engineering geological information for the development and utilization of the beach area. |
