摘　　要：近年来,利用无人机平台搭载航空电磁勘探设备已经成为一种发展趋势,本文首先阐述了半航空瞬变电磁系统在国内外的研究进展,然后介绍了一种全新的利用无人直升机搭载的半航空瞬变电磁勘探系统(S-ATEM).S-ATEM系统由发射子系统、接收子系统、数据处理子系统和飞行平台组成,本文对各子系统关键技术及系统指标进行了详细阐述.S-ATEM系统采用无人直升机作为飞行平台,具有发射功率大、长航时、多分量、大探深、机动灵活、可移植性强等特点.利用S-ATEM系统在山东昌邑莲花山铁矿区开展了电磁探测飞行试验,并将探测结果与已知钻孔资料进行了比对,结果表明S-ATEM能够有效反映地下介质的电阻率变化,验证了S-ATEM系统的有效性和实用性.In recent years,it has become a trend to equip the airborne electromagnetic equipment on UAV（ Unmanned Aerial Vehicles） platform. This paper describes the development of semiairborne transient electromagnetic system both in China and abroad,and then introduced a new semi-airborne transient electromagnetic system（ S-ATEM） and its application with UAV platform. S-ATEM system consists of transmitter,receiver,data processing and UAV platform. The new EM system has many advantages such as large transmission power, long-endurance working, multi-component measurement,large deep exploration and portability. The practical prototype has been successfully completed and a field survey is successfully carried out at Lianhuashan iron deposit in Shandong province. Compare the result of S-ATEM system to the borehole data,the comparison result indicates that S-ATEM system can reflect the resistivity distribution of underground effectively.
