【摘要】：近年来,随着无线电技术的迅猛发展和无线电设备的广泛应用,考试无线电作弊行为日益猖獗。为防范和打击利用无线电设备进行考试作弊的行为,维护公正、公平的考试秩序和空中电波秩序,考试无线电安全保障工作受到了广大考试主管部门和无线电管理机构的密切关注。怎样在现有条件下将无线电技术与考试保障工作有效结合,进一步做好考试保障工作,是值得研究和学习的。就目前的实际情况来看,保障工作中存在监测自动化水平不高等问题。本文主要研究内容包括以下几点:1、无线电作弊设备的技术特点,研究作弊信号的辨别方法。2、对考试保障工作中如何提高监测中频段扫描工作的自动化水平进行研究,提出三种解决方法:一是,使用阈值谱监测技术;二是,使用触发测量监测技术;三是,完善基础数据库,进行实时数据比对。3、研究无线电测向和定位技术,对用到的无线电监测系统和设备进行技术分析。适当分析这几种测向定位技术的优缺点,在考试保障工作中,应根据实际情况选用不同的设备及技术方法。4、对无线电干扰压制技术在实际工作中的应用进行研究,总结实际工作中的经验,提出一套压制无线电考试作弊信号的方法。
[Abstract]:In recent years, with the rapid development of radio technology and the wide application of radio equipment, cheating in examination radio is increasingly rampant. Fair test order and airwaves order. The examination radio safety and security work has been paid close attention by the examination department and the radio administration organization. How to combine the radio technology and the examination guarantee work effectively under the present condition. It is worth studying and studying to do the test guarantee work well further. According to the actual situation at present, there are some problems such as the low level of monitoring automation in the security work. The main research contents of this paper include the following points: 1. The technical characteristics of radio cheating equipment, the study of cheating signal discrimination method. 2, how to improve the automatic level of frequency band scanning in the examination guarantee work. Three solutions are proposed: one is to use threshold spectrum monitoring technology; Second, the use of trigger measurement and monitoring technology; Third, improve the basic database, carry out real-time data comparison. 3, research radio direction finding and positioning technology. The technical analysis of the radio monitoring system and equipment is carried out. The advantages and disadvantages of these techniques are properly analyzed. Different equipments and technical methods should be selected according to the actual situation in the examination guarantee work. This paper studies the application of radio interference suppression technology in practical work, summarizes the experience in practical work, and puts forward a set of methods to suppress the cheating signals in radio examinations.
