4) Dead detection zone
探测死区
5) blind zone
探测盲区
1.
Since inductive load transient electromagnetic method for shallow survey adopts ramp switch-off current as inducing source, a blind zone near ground surface will exist even though the ramp correcting method is used, and will result in low resolution and precision for shallow detection.
针对这一问题,研究了全程瞬变电磁场与斜阶跃波的关断时间与接收探头频率特性之间的关系,揭示了早期瞬变电磁场信号发生畸变和影响浅层瞬变电磁探测的根本原因,提出了当瞬变电磁测量系统在电流关断开始时刻记录全程瞬变响应和发射电流波形时,并且接收探头的位置和谐振频率已知,就可以通过数值计算方法从根本上剔除接收探头对早期瞬变信号的影响,从而实现浅层近地表探测,缩短探测盲区。
