Based on CC1000 wireless sensor networks development platform, the odometer location error is corrected by measuring RSSI parameter and using maximumsignalmethod.
在CC 1000无线传感器开发平台上，对节点RSSI参数进行测量并采用最大信号法定点修正定位误差。

The transient electromagnetic method has a maximum depth because of continuous attenuation by transmission of electromagnetic signal in underground.
由于电磁信号在地下传播时不断衰减，瞬变电磁测深法有一个最大探测深度。

A filtering method based on wavelet transform with local maximum value was discussed. The method could distinguish signal from the noise according to the different features of scale change.
