摘　　要：国内在大功率时间域航空电磁法的应用上,还不像航空磁测、航空放射性测量那样普及,起步也较晚,由于历史原因目前技术尚不成熟,大家对其设备、飞行方法、数据采集等方面了解的还不是很多。这里介绍了TS-150型时间域航空电磁系统的设备组成、发射机原理、系统工作的原理、系统中的补偿原理、采集数据的取样方式、数据的记录单位、系统的测量噪声及测线飞行测量结果的nT/s平面色阶图、测线剖面nT/s异常图的初步解释推断等内容,并进行了实验验证。Domestic in high power application of aviation electrical method in time domain don't like aviation magnetic survey,airborne radioactivity survey,and aviation electrical method.It started relatively late due to historical reason technology that is not mature at present.The knowledges of the equipment,data acquisition and even the flight methods are not well clear.TS-150 in the type of airborne electromagnetic system in time domain,including equipment composition,transmitter principle,system principle,the compensation principle,sampling methods,data acquisition data record unit are introduced.The system noise and fly line measurement results of the nT/s flat face figure,and line profile nT/s preliminary interpretation of anomalies are also introduced.
