在瞬变电磁勘探法中 ,早期信号对研究浅层地质结构是非常重要的。然而 ,早期信号的准确获得往往受到接收系统和采样方法的限制 ,特别是接收线圈中固有的暂态过程对测量的影响很大 ,因而限制了瞬变电磁勘探法在浅层地质勘探领域的推广。本文提出了一种适用于早期信号测量的程控接收天线 ,实验表明它对消除接收线圈中影响早期信号测量的暂态过程十分有效 In transient electromagnetic prospecting, early signals are very important for the study of shallow geological formations. However, the accurate acquisition of early signals is often limited by the receiving system and the sampling method. In particular, the inherent transient process in the receiving coil greatly influences the measurement, thus limiting the promotion of transient electromagnetic prospecting in the field of shallow geological exploration . This paper presents a programmable receive antenna suitable for early signal measurement. Experiments show that it is very effective in eliminating the transient process affecting the early signal measurement in the receive coil
