摘　　要：随着现代信息化战争的发展,集雷达、电子战、通信等多种功能于一身的一体化雷达是雷达发展的必然趋势。本文介绍了一种基于FPGA的一体化数字接收机的设计与实现,描述了接收机的硬件架构设计、固件设计和最后的指标测试结果。接收机采用子母板架构进行设计,采用中频直采、数字正交解调、数字滤波、数字下变频等技术,实现了雷达、电子战一体化的数据采集。With the development of modem information warfare, the integrative radar with radar, electronic warefare（EW）, communications and other functions becomes the inevitable trend of the development of radar. This paper introduces the design of an integrated digital receiver based on FPGA, the hardware design, software design and test results of the receiver are described in details. Using sub-motherboard architecture, with the technologies of direct IF sampling, digital quadrature demodulation, digital filtering and digital down conversion, the integration of radar data acquisition and EW data acquisition is implemented on the receiver.
