【摘要】：無線電新興技術(shù)、新型業(yè)務(wù)雨后春筍般層見疊出,無線電設(shè)施需求增長迅猛,致使電磁頻譜環(huán)境惡化嚴重。網(wǎng)格化無線電監(jiān)測被提上日程。該種監(jiān)測模式最顯著的特點在于海量監(jiān)測數(shù)據(jù)打底,分別在無線電監(jiān)測技術(shù)、業(yè)務(wù)應(yīng)用、行政管理三方面加強聯(lián)系。本文從介紹網(wǎng)格化無線電監(jiān)測系統(tǒng)的基礎(chǔ)知識入手,對在建設(shè)網(wǎng)格化無線電監(jiān)測系統(tǒng)時面臨的站點覆蓋范圍的確定等問題進行重點研究,主要工作有以下幾點:一、首先,針對當前無線電監(jiān)測面臨的困境進行概述,如無線通信設(shè)備逐漸向微型化、數(shù)字化、智能化發(fā)展,傳統(tǒng)的大型監(jiān)測站對遠距離、低輻射功率監(jiān)測能力不足,對區(qū)劃整體的頻譜態(tài)勢無法評估。在此提出新興的網(wǎng)格化的無線電監(jiān)測方式,對其基本概念、特征、功能進行了介紹。二、針對網(wǎng)格化無線電監(jiān)測系統(tǒng)在建設(shè)時面臨的主要挑戰(zhàn)、監(jiān)測站點的選址和覆蓋范圍等問題進行探討,分析不同無線電波傳播模型,并對傳輸距離進行計算。三、利用現(xiàn)有技術(shù)通過實地測量實驗與軟件智能仿真,對網(wǎng)格化無線電監(jiān)測系統(tǒng)中單個監(jiān)測站點的覆蓋范圍進行對比,總結(jié)規(guī)律,為今后實際建設(shè)陜西省西安市網(wǎng)格化無線電監(jiān)測系統(tǒng)打下一定理論基礎(chǔ)。
[Abstract]:With the emergence of new radio technologies and the rapid growth of demand for radio facilities, the electromagnetic spectrum environment has deteriorated seriously. Grid radio monitoring has been put on the agenda. This paper begins with introducing the basic knowledge of grid radio monitoring system, and focuses on the determination of site coverage when building grid radio monitoring system. Communication equipment is gradually developing towards miniaturization, digitization and intellectualization. Traditional large-scale monitoring stations have insufficient ability to monitor long-distance and low-radiation power, which makes it impossible to assess the overall spectrum situation of the zoning. The main challenges faced by the electric monitoring system in construction, the location and coverage of monitoring stations are discussed, and different radio wave propagation models are analyzed, and the transmission distance is calculated. Thirdly, a single monitoring station in the grid radio monitoring system is realized by field measurement experiment and software intelligent simulation using the existing technology. The coverage of the grid radio monitoring system in Xi'an of Shaanxi Province is compared and the laws are summarized.
