摘要
为解决基于PC104平台的超短波频谱监测接收机研制过程中的高速数据采集和采样信号实时高性能处理问题,介绍一种模块化设计的基于PC104Plus总线的双通道数字处理平台;主要阐述系统硬件结构、PCI9054本地端逻辑设计、WDM功能驱动程序设计、DSP数据调度以及性能测试等;实际测试证明,该数字处理平台能够满足超短波频谱监测设备对中频数字信号处理性能的要求,30~3000MHz全频段搜索速度快、频率分辨率高,在综合集成与应用方面具有创新性。
In order to solve the high speed data acquisition and sampled signal real--time high--performance processing issues in the de- velopment of VHF/UHF radio spectrum monitoring receiver based on the PC104 platform, describes a dual--channel digital processing plat- form based on PC104Plus bus using modular designing method. Mainly expounds the system hardware architecture, PCI9054 local--side logic design, WDM function driver design, DSP data scheduling, and performance testing. Actual test proved that the very digital processing plat- form hold innovative application property in comprehensive integration studying which can meet the USW radio spectrum monitoring equip- ment to IF digital signal processing performance requirements, such as high speed 30M^3000MHz full--band searching and good frequency resolution performance.
