摘　　要：针对目前由RISC微处理器(ARM,advanced RISC machines)与现场可编程门阵列(FPGA,field programmable gate array)构成的传统抗干扰全球定位系统(GPS,global positioning system)接收机的体积大、成本高、功耗高等缺点,提出采用威视锐Y320平台构成的抗干扰GPS接收机实时捕获模块的设计方案,该平台集成了ZYNQ-XC7Z020-CLG400ABX1829芯片和AD9361射频收发器。利用实验室现有抗干扰GPS接收机平台上的捕获算法,对原有算法中捕获门限算法进行优化,同时将捕获卫星数提升为37颗,并在新硬件平台上实现捕获功能。实验结果表明,新硬件平台实现的捕获算法能有效捕获GPS卫星,满足GPS接收机捕获模块的设计要求,为实现跟踪、定位、抗干扰等功能提供基础。Aiming at the disadvantages of large size, high power consumption and high cost of traditional anti-jamming global positioning system(GPS) receivers composed of advanced RISC machines(ARM) and field programmable gate array(FPGA), a design scheme of anti-jamming GPS with real-time acquisition module composed of Wei Shi Rui Y320 platform is proposed. The platform integrates AD9361 RF agile transceiver and ZYNQ-XC7 Z020-CLG400 ABX1829 chip. Using the acquisition algorithm on the existing anti-jamming GPS receiver platform in the laboratory, the acquisition threshold algorithm in the original algorithm is optimized, and the number of acquired satellites is increased to 37, and the acquisition function is realized on the new hardware platform. Results show that the acquisition algorithm implemented by the new hardware platform can effectively capture GPS satellites, meet the requirements of GPS receiver acquisition module design, and provide a basis for tracking, positioning, and anti-jamming functions.
