航磁测量中飞行高度质量控制的方法技术

THE TECHNIQUE FOR CONTROLLING FLYING ALTITUDE QUALITY IN AEROMAGNETIC SURVEY

在青藏高原中西部开展的 1∶10 0万高精度航磁概查中 ,能否获得高质量的测量效果 ,关键在于能否在野外作业中保持较低的飞行高度。在保证飞行安全的前提下 ,根据测区的地形、气象条件和飞机性能 ,提出了旨在能有效地降低飞行高度的新的测量方法 ,取得了预期效果 ,有一定的推广意义。

In the 1∶1 000 000 high precision aeromagnetic reconnaissance performed in central and western Qinghai Tibet plateau, the acquirement of high quality surveying result depends largely on keeping relatively low flying altitude in field work. With the prerequisite that the flying safety is guaranteed, this paper puts forward a new surveying method aiming at effectively lowering the flying altitude in accordance with the topographic and meteorological conditions of the surveyed area and the performance of the aircraft. Practice shows that this method can yield satisfactory result and hence deserves popularization.
