摘要
优化了航空瞬变电磁法一维正演算法,采用新的汉克尔变换系数,理论上提高了正演的精度.提出了航空瞬变电磁法一维反演算法——模型交替调整反演算法,阐述了该算法的原理和计算方法,编写出反演程序,以已知模型正演响应作为实测数据,对若干典型模型进行了反演计算,取得了较理想的反演效果,与Zohdy法相比,该方法有更高的精度.
First we optimized the ATEM 1-D forward algorithm with new Hankel filters, then theoretically higher precision can be acquired. We developed a new ATEM 1-D inverse algorithm -- alternate model adjustment method. The principle was discussed and the algorithm was described. The program was worked out, and applied for several typical models' forward responses, the good results prove its advantages. Compared with Zohdy's method, this method can achieve higher precision.
