一种基于CPCI-E总线的频谱监测设备设计与实现

ANovel Scheme of Spectrum Monitoring Direction-finding Device Basedon CPCI-E Bus

针对传统的频谱监测设备存在功能单一、通用性差、设备量大和集成度低等缺点,提出了一种新的基于CPCI-E总线的频谱监测测向设备设计方法。该方法基于标准化和模块化的设计思路,采用了CPCI-E总线技术,既提升了设备数据吞吐能力和信号处理性能,又提升了设备功能重构和模块互换能力。新设备不仅具有瞬时监测频段宽、测向精度高和自动化程度高等特点,且能够满足于多信号、多模式和多体制的频谱监测测向需求。

Considering the disadvantages of traditional spectrum monitoring and direction-finding devices such as single function,poor commonality and low integration degree,a novel scheme of spectrum monitoring direction-finding device based on CPCI-E bus is proposed. The scheme is based on standard and modular design ideas and uses CPCI-E bus technology,which not only improves the data throughput and signal processing performance,but also enhances the device ＇s ability of function reconstruction and module interchanging. The new device not only has the characteristics of wide instantaneous monitoring frequency band,high accuracy and high automation degree,but also can meet the requirements of multi-signal,multi-mode and multi-system spectrum monitoring and direction finding.
