基于LabWindows/CVI的雷达信号分析软件设计

针对当前传统信号分析仪器对复杂雷达信号分析测试功能单一、使用不便等问题,提出了采用虚拟仪器开发具有多域联合分析功能的雷达信号分析软件的设计思想,简述了软件结构与各模块功能,并给出了基于LabWindows/CVI的软件具体设计。最终,通过对雷达中常用的线性调频信号进行测试,验证了该软件的可靠性与实用性。与同类软件相比,雷达信号分析软件具有操作简单、误差小、精度高、可对多种雷达信号进行一键式分析测量和易于软件升级等优点。

Design of Radar Signal Analysis Software Based on LabWindows/CVI

This paper presents a design idea of radar signal analysis software with a multi-domain conjoint analysis function based on virtual instruments in view of the single function,inconvenient use of the traditional signal analysis instrument existing in the analysis of complex radar signal.Firstly,the structure of software and the function of each module are described briefly,and then the software design based on LabWindows/CVI is brought forward in details.Finally,a widely-used linear frequency modulation signal is used to validate the reliability and practicality of the software.Compared with the similar software,the radar signal analysis software has the advantages of easy operation,small error,high precision,easy upgrade,and one-touch analysis on various radar signals.
