摘　　要：目前,航空电磁测量系统的研制、方法理论研究以及数据处理解释软件开发逐渐成为国内研究热点,针对以上问题,本文利用Maxwell内置的正演模拟算法,通过二维薄板模型的电磁响应曲线分析,对目前国外广泛使用的直升机和固定翼航空电磁测量系统的空间分辨率和探测深度进行了综合研究及对比分析,在正演曲线剖面图上清晰得到了两种系统各自的特点,为理论研究时间域航空电磁响应的分布规律提供了新的思路,也为研究航空电磁反演奠定了基础。At present, the design of airborne electromagnetic measurement, the researches on its method and theory and the development of data processing and interpretation soft- ware have gradually become hot research topics. In view of the questions mentioned above, this paper uses the main program in the Maxwell software, and discusses the depth pene- tration and spatial resolution between Helicopter and Fixed--Wing time--domain electro- magnetic systems, so the characteristics of the two kinds of systems have been got from the clear forward curve profile,which provides a new way of thinking for the distribution of the time domain airborne electromagnetic response, but also for laying the basis of studying the airborne electromagnetic inversion.
