摘　　要：地质雷达探测是分辨率较高的一种地质勘察手段,影响地质雷达探测的主要干扰因素有地面耦合效应、地表块状物和长条状物干扰、建筑物的干扰及空中高压电缆干扰等。在探测过程中应尽量避开干扰源,优化数据采集过程,进行图像后期处理,将噪声信号进行抑制,对有效信号进行放大,以利于有效目标体的识别。The detection with GPR is one of the geological explorative means with high differentiable rate. The major factors to affect the detection include the ground coupled effect, the disturbance of the block or long-shaped objects on the ground surface, and the disturbance of the buildings and the midair high-voltage cables. The disturbing sources should be avoided in the process, the data collecting procedure be optimized, the noise signal be restrained and the useful image be magnified, which are favorable to the identification of the valid targets.
