摘　　要：文章基于广域电磁法(WFEM)的基本理论,结合当前资源勘查所面临的问题及航空物探的发展现状,主要从基本理论、装备研究、应用测试3个主要方面对航空广域电磁法进行了初步探索。通过探索我们认识到,航空广域电磁数据采集质量易受飞机飞行姿态及飞机本体噪声的影响,但是大于100 Hz的高频段具有更好的数据质量和实际工程应用的可行性。Based on the basic theory of wide-field electromagnetic method(WFEM)and combined with the current problems of resource exploration and the development status of aviation geophysical prospecting,the authors mainly deal with the aviation wide-area electromagnetic method in three main aspects as a preliminary exploration:basic theory,equipment research and application testing.It is held that the quality of aviation wide-area electromagnetic data collection is susceptible to aircraft flight attitude and aircraft body noise,and high frequency bands greater than 100 Hz have better data quality and practical engineering application feasibility.
