摘要
相位激电法的观测信号是总场,信号幅值相对较大,因而所需要的发射功率相对较小、设备较为轻便。在相位计算过程中由于采用了基于信号和噪声在时间特性上的差别,提取或恢复弱信号的相关检测技术,明显提升了仪器的抗干扰能力。这里以相位激电方法在福建某矿区的应用效果为例,说明相位激电法在强干扰和接地困难条件下,可获得可靠的观测数据,实现了对目标地质体的有效探测。
The total electric field measurement using phase-IP method,compared with the conventional time domain IP,the sending power of phase-IP required is smaller and the equipment is more portable.By the use of correlation detection technology and new electronic technique in phase-IP instrument,it improves the anti-jamming capability and the measuring accuracy of the instrument markedly.The trial effect that tested at a certain ore in Fujian is discussed in this paper.The result indicates that phase-IP can get reliable data,and can probe the objective geologic body effectively in strong interference and difficult grounding area.
