摘要
本文提出了一种基于数字波束形成(Digital Beam Forming,DBF)雷达体制的最小软件化综合处理机设计。采用国产化的模数转换器(Analog-to-digital converter,ADC)、直接数字式频率合成器(Direct Digital Synthesizer,DDS)、现场可编程逻辑门阵列(Field Programmable Gate Array,FPGA)、数字信号处理器(Digital Signal Processor,DSP)等芯片实现软件化参数可任意配置的波形产生、波束控制、数字波束形成、信号处理等功能。此外,通过级联该最小综合处理机可实现DBF体制雷达规模的可扩展性,即通过多级流水、系统同步和系统校准实现多种规模的阵列信号的数字波束形成以及相关信号处理。
This paper proposes a minimal software integrated processor design based on DBF radar system.Using domestically produced ADC,DDS,FPGA,DSP and other chips to realize the functions of waveform generation,beam control,digital beam forming,signal processing and so on,which can be arbitrarily configured by software parameters.In addition,by cascading the minimal integrated processors,the scalability of the DBF system radar can be realized,That is,through multi-stage pipeline,system synchronization and system calibration,digital beam forming and related signal processing of array signals of various scales are realized.
