【摘要】：隨著無線電資源的廣泛使用,人們對電磁環(huán)境監(jiān)測定位設(shè)備的需求不斷增加,尤其是對飛機場防電磁干擾監(jiān)測儀等小范圍環(huán)境內(nèi)頻譜管理設(shè)備的需求。因此,設(shè)計一套便攜式、低成本、功能齊全的網(wǎng)絡(luò)化無源監(jiān)測定位系統(tǒng)具有重要的使用價值。本文基于時差定位系統(tǒng),主要設(shè)計和研究軟件系統(tǒng)部分,并對時差估計算法進行分析和研究。首先,給出一種工程中較為實用的改進型精確時差估計方法,并分析了時差測量誤差對定位性能的影響。在算法驗證基礎(chǔ)上,實現(xiàn)了無源定位系統(tǒng)的軟件設(shè)計,重點完成了界面顯示、參數(shù)配置、數(shù)據(jù)通信,以及數(shù)據(jù)存儲等模塊的功能實現(xiàn)。整個軟件系統(tǒng)基于VS2010平臺和C++語言進行開發(fā)。其次,采用了模塊化軟件設(shè)計方法,對各個功能模塊進行單獨設(shè)計和測試。通過設(shè)計各功能模塊完成了以下工作:(1)通過繪圖顯示模塊實現(xiàn)了二維曲線圖、柱狀圖和彩色瀑布圖的顯示;(2)通過參數(shù)配置模塊實現(xiàn)了對遠程硬件系統(tǒng)的控制和管理;(3)通過數(shù)據(jù)通信模塊實現(xiàn)了整個無源定位系統(tǒng)的網(wǎng)絡(luò)化;(4)通過數(shù)據(jù)存儲模塊實現(xiàn)了系統(tǒng)數(shù)據(jù)的存儲,方便用戶進行離線分析。最后,通過多線程設(shè)計方案,將各個功能模塊進行協(xié)調(diào)集成,完成了整個無源時差定位軟件系統(tǒng)的設(shè)計與實現(xiàn)。該軟件系統(tǒng)具有很好的精確授時功能,在時鐘源同步情況下,時差測量誤差小于100ns。該軟件具有固定頻率掃描、頻段掃描、寬帶掃描、信道掃描和全景掃描等模式,這些模式的工作帶寬最高可達20MHz,且工作頻率范圍為20MHz~3.6GHz。軟件界面簡潔美觀,操作方便,具有信號監(jiān)測、信號檢測和信號統(tǒng)計分析等多種功能。
[Abstract]:With the wide use of radio resources, the demand for electromagnetic environment monitoring and positioning equipment is increasing, especially the demand for spectrum management equipment in small environment such as airport electromagnetic interference monitor. Therefore, the design of a portable, low-cost, full-featured networked passive monitoring and positioning system has an important use value. In this paper, based on the time difference location system, the software system is designed and studied, and the algorithm of time difference estimation is analyzed and studied. Firstly, an improved accurate time difference estimation method is presented, and the influence of the time difference measurement error on the positioning performance is analyzed. On the basis of algorithm verification, the software design of passive positioning system is realized, and the functions of interface display, parameter configuration, data communication and data storage are implemented. The whole software system is based on VS2010 platform and C language. Secondly, the modular software design method is used to design and test each functional module separately. The following work is accomplished by designing each functional module: 1) the two-dimensional graph is realized by drawing and displaying module. The display of histogram and color waterfall is realized by parameter configuration module, the control and management of remote hardware system is realized by means of data communication module, the network of the whole passive positioning system is realized by the data communication module, and the data storage module is used to realize the control and management of the remote hardware system The storage of system data is realized. It is convenient for users to do off-line analysis. Finally, the design and implementation of the whole passive TDOA software system is completed through the multi-thread design scheme and the coordination and integration of each functional module. The software system has a good precision timing function. In the case of clock source synchronization, the time difference measurement error is less than 100ns. The software has fixed frequency scanning, frequency band scanning, wideband scanning, channel scanning and panoramic scanning. The operating bandwidth of these modes is up to 20 MHz, and the operating frequency range is 3.6 GHz. The software interface is simple and beautiful, easy to operate, with signal monitoring, signal detection and signal statistical analysis and other functions.
