摘　　要：为了提高探地雷达接收机的性能,从时域接收机原理着手,采用降低旁通效应、降低取样脉冲泄漏、合理选择元器件、改进电源设计、优化电路设计及结构设计等技术方法进行了分析研究,并进行了测试和对比实验,证明该技术措施明显提高了接收机的性能。该技术措施也适用于其他超宽带时域接收机设计,部分措施对通用雷达频域接收机也有一定借鉴作用。In order to improve the receiver performance of ground penetrating radar（GPR）,based on the timedomain receiver principle,several technical measures are adopted,such as reduction of bypass effect,reduction of sampling pulse leaking,selection of proper devices,optimized design of power supply,circuit and structure. The testing and comparison experiments were accomplished. The technical measures greatly improved the performance of the receiver. The technical measures are suitable for other wideband timedomain receivers. Some of the technical measures have a certain reference for universal frequencydomain receivers.
