结合了一种米波段DBF 体制雷达的研制，提出一种基于CPCI 总线的数字接收机。它由多块单板完成10 通道数字接收的标准6U 板卡、SCSI 磁盘阵列、内定时控制板和互连的二次底板构成，具有集成度高、模块化强、动态范围大等优点，已实际应用于雷达的外场联试。由于其通用性，经过软件的升级、移植，也可广泛应用于通讯、声纳、医疗设备等领域。关键词：DBF 米波雷达 数字接收机 CPCIImplementation of Metre Wave Band DBF Radar Digital receiver Tao,Qingchang Xu,Chengfa Abstract: The implementation of a digital receiver platform based on CPCI bus are discussed which is combined with the development of a metre wave band DBF radar. The digital receiver has been applied to outfielding debgugging , which consist of SCSI Raid ,inner timer , backplane for interlink and several standard 6U board who handles 10 channels digital receiving. It has some merit such as high integration degree, powerful modularization and big dynamic rang, so it can be used in other wild field such as communications, sonars and medical equipments.Key word: DBF , Metre wave band Radar, Digital Receiver, CPCI
