Abstract

Ray intercept algorithm is the key factor to improve the speed of radio tomography. A second scan search algorithm is proposed to acquire the intersecting point coordinates between ray and gridlines. For this algorithm , successive scanning and sorting of intersection sequence would consume much computing time and memory. In order to avoid successive scanning, search variables have been introduced into search procedure to reduced scan range. Search progress has been improved to omit the sort process at the same time. Through these two improvements, the number of searches has been greatly reduced. The algorithm proposed in this paper is proved to be effective and accurate by electromagnetic wave amplitude tomography inversion calculation of a certain coal face fault structure perspective data.
