摘要 以Impulse直升机航电水平共面装置系统参数为基础,介绍了正演公式,根据视电阻率转换的2种转换模型——均匀半空间和似层状半空间模型
,分别介绍了一维搜索法和列线图查找法这两种视电阻率转换方法。根据应用实例,通过对比视电阻率转换图,探讨这2种方法的转换效果。
Abstract :Based on the parameters of the horizontal coplanar system of Impulse and adopting the forward formula and the homogeneous
halfspace and pseudolayer halfspace model, this paper describes the algorithms for onedimensional search and phasor diagram
search. These algorithms usually deal with different models. One algorithm is weighed against the other by the resistivity
conversion of actually measured data, and the application effect of resistivity conversion is validated by the image of resistivity.
