前言脉冲式航空电磁系统,是六十年代加拿大发展起来的新型航电系统,对探测良导性矿床,特别是硫化矿床,有良好效果,具有勘探深度大、覆盖层影响小等优点。为“独立自主、自力更生”地发展我国航电事业,根据冶金部指示,我们从1971年开始研制脉冲式航空电磁系统。结合我国具体情况,我们首先研制了直-五飞机的短吊仑方案,与国外采用的长吊仑
Introduction The pulsed airborne electromagnetic system is a new avionics system developed in Canada in the 1960s. It has good effect on detecting good-conductivity ore deposits, especially sulphide ore deposits, and has the advantages of large exploration depth and little influence of overburden. In order to develop China’s avionics cause for “independence and self-reliance,” we started to develop a pulsed airborne electromagnetic system from 1971 on instruction from the Ministry of Metallurgy. Combined with our specific situation, we first developed a straight-fifth aircraft short shenlan program, and abroad long sarl
