| 摘 要： | 激励脉冲的脉宽改变使探地雷达发射天线产生明显的旁瓣辐射回波，对该种波成分的研究在探地雷达的应用中有一定的理论和实际意义。从频域中各频率分量下旁瓣辐射回波电场强度占总接收波形电场强度比例的角度出发，研究了旁瓣辐射回波的提取方法，并在实际应用中将该方法所得结果与实测结果相比较。结果表明，该方法可以较好地从接收波形中提取出旁瓣辐射回波，在一定程度上验证了该方法的合理性。

| Abstract: | The obvious echoes of the side-lobe transmitting waves are caused by the transmitting antenna working on the condition of a stimulation pulse with abnormal pulse width. The studies of the properties of the echoes are significant in theory and applications on the GPR. Based on the ratio of the electric field intensity from the echoes of the side transmitting waves to the total receiving electric field intensities, a method of the echoes of the side-lobe transmitting waves is presented. The results obtained from an application with this method are compared with the trial data. The comparisons show that the agreement between the echoes acquired using this method and the trial data is good. The rationality of the method is approved. |
