| 摘 要： | 为实现混场源电磁法应用的电性源信号发射,弥补天然电磁场信号弱的不足,设计了一种基于多频信号的混场源电磁发射系统.多频信号具有多个频率成份且各成份能量均衡的特点,发射该类信号可使系统一次发射多个频点,大大提高发射效率.同时,发射系统发出的多频信号为近似对数间隔频点的信号,更适合接收系统对数据的处理.实验表明:发射的多频信号能够满足混场源电磁法的探测要求,具有与磁性源系统相似的探测效果.

| Abstract: | To transmit electricity-signal source applied on hybrid-source magneto tellurics(HSMT)so that the deficiency of nature electromagnetic signal weak can be reparable,an HSMT transmitting system is designed based on multi-frequency signal.Having multi-frequency and the equilibrium energy of all frequency of the multi-frequency signal,the system can transmit multi-frequency by transmitting it so that the transmitting efficiency is improved obviously.The frequency interval of the transmitting signal approximates... |
