In order to improve the receiver performance of ground penetrating radar(GPR),based on the time?domain re?ceiver principle,several technical measures are adopted,such as reduction of by?pass effect,reduction of sampling pulse lea?king,selection of proper devices,optimized design of power supply,circuit and structure. The testing and comparison experi?ments were accomplished. The technical measures greatly improved the performance of the receiver. The technical measures are suitable for other wide?band time?domain receivers. Some of the technical measures have a certain reference for universal frequen?cy?domain receivers.
