The Design And Implementation Of The Radio Monitoring And Direction Finding Software

In order to get radio interference monitoring more efficiently and ensure flightsafety, the advanced techniques must be involved and a high efficient and applied radiomonitoring system must be developed, with which the radio frequency and wave can bemeasured, the unlawful broadcasting station and Interference can be located, and thecivil aviation management frequency can be monitored, recorded and analyzed to findinterference and make a alarm.In this dissertation, based on the function analysis of the old radio monitoringsystem in the company, the software framework was redesigned, and many functionswere added, such as quick scan, field intensity location measuring, cross plottinglocation, inter-modulation interference analysis, monitoring data analysis, and so on.Based on the C/S framework, the important contents of the function, theframework, the customer service communication message agreement, the exteriorinterface agreement and the equipment server were designed generally. And the generalfunctions of monitoring, direction finding, listening monitoring and TV monitoringwere achieved. At the same time, the function of broadcasting station batch processmeasuring, important frequency batch process measurement, interference analysis andlocated interference were also made realization.In the dissertation, the main modules were designed in detail to achieve the mainfunctions including data quick scan, historical data and field intensity analysis and thenoise location and trend analysis, and so on.In the dissertation, the multifunctional and auto control measurement function wasdesigned especially to reach the goal of multifunction, multitask, multi-user supporting,multitask supporting in real time, and time division multitask supporting. Simultaneity,a perfect system resource management technology was got. Ultimately, the test resultsindicated that the system has reached the prospective goal basically.
