多通道时频信号监测评估测试系统的设计与实现

摘要

In order to effectively monitor,evaluate and test the multi - channel time - frequency signals,the monitoring,evaluating and testing system based on UDP protocol for multi - channel time - frequency signals is designed and developed. The principle of system operation and the design of hardware is elaborated and software are given; some of the key technologies in acquisition of multi - channel time - frequency signals are introduced emphatically. The software evaluation and report generation fucitions are realized by C# and Matlab. The system has been successfully applied to monitor and evaluate the time - frequency signals of certain navigation facility; it is also used to provide supporting data for analyzing,locating,handling failures of navigation facility.%为了有效地实现对多路时频信号的监测、评估与测试,设计研发了一种基于UDP协议的多通道时频信号监测评估测试系统.阐述了系统的工作原理,给出了系统的软硬件设计,重点介绍了实现多通道时频信号采集的关键技术.软件评估与报告生成功能通过C#与Matlab混合编程实现.系统现已成功应用于某导航装备的时频信号监测评估,为分析、定位、处置导航装备故障提供数据支持.
