The familiar electromagnetic interference is discussed in the measurement of spacecraft environment testing . for antijamming , the electromagnetic interference is analyzed and the antijamming technique is brought forward 摘要介绍了在环境试验设备计量测试过程中常见的一些电磁干扰现象，通过对这些现象的分析，提出了一些解决问题的措施，最终达到抗干扰的目的。
To deal with the wide application of electronic - counter , electronic jamming and anti - radiation missile , it is required to enhance the viability and antijamming ability of each electronic reconnaissance equipment 随着新技术、新方法在军事领域的应用,电子对抗、电子干扰、反辐射导弹等技术均有了长足的发展,这对电子侦察设备的生存能力和抗干扰能力提出了越来越高的要求。
Then this paper presents the software flow , divide the realization of the system into different function modules for the purpose of software maintenance and amendment . the paper also gives an outline of some means of debug and software antijamming measure 并给出了以上系统设计时的软件流程，将各系统的实现分为不同功能模块，以便于软件维护和修改，同时简单介绍了调试时的一些方法和软件抗干扰措施。
Compared with conventional lan , the wlan has a lot of advantages , such as movability , convenience to access , confidentiality , antijamming , easy to maintain and low cost . now , the most widely used wlan technology is based on ieee 802 . 11 standard . however , the traditional security methods , for example wep , are proved not insecure 与传统的有线网络相比,无线局域网wlan ( wirelesslan )具有可移动性、用户接入灵活、保密性强、抗干扰性好、维护方便以及良好的性价比等优点,现在应用最广泛的就是基于ieee802 . 11标准的无线局域网技术。
Spread spectrum communication is paid more attention to the advantage of good message privacy , antijamming and mutiple access in the world , it shows strong vitality on the side of measuring distance , antenna measure , mine communication , tactics communication , muti - access application , mobile communication and so on 扩展频谱通信以其保密性好、抗干扰能力强、多址性等优点成为目前世界上广为受重视的一种通信技术，它在测距、天线测量、矿井通信、战术通信、多址应用、移动通信等方面都显示了强大的生命力。
For the electronic proving ground reality , the advantages and shortcomings of several evaluation criteria are synthetically compared through studing jamming and antijamming effects between oppressive jamming and the target search radar . according to the ultimate effectiveness criterion , the method of using the tactics and technology indices to evaluate the radar jamming and antijamming effects in quantity is discussed . the quantitative grade judgement on jamming and antijamming effects are presented 从电子装备试验靶场的实际出发，通过研究压制性干扰对目标搜索雷达的干扰，以及后者对前者的抗干扰效果，综合比较了几种评估准则的优劣，依据最终效果准则，分别论述了用技术指标和战术指标定量评估雷达干扰抗干扰效果的方法，提出了干扰抗干扰效果的定量等级评判，并通过信干比、抗干扰改善因子，将战术、技术指标评估统一起来，二者在实质上是等效的。
In addition , this paper not only makes detailed illustration on hardware but also on software design in respect of field anti - jamming performance . especially in software design , it adopts methods of " software trap " and " sign position setting " greatly improving the antijamming capacity of accumulator 另外，本文在现场抗干扰方面，不仅在硬件设计上作出了明确的阐述，而且在软件设计上，采用了“软件陷阱法”和“标志位设置法” ，使得积算仪的抗干扰性能，得到大大的提高。
At last the computer processes the data and outputs reporting tables , curves and analyzes the results . the communication between the underground communication extension and the ground receiving mainframe of the monitoring system uses rds transmitting technology which has high transmitting efficie ncy and strong antijamming ability 计算机做最后的数据处理、输出报表、曲线及分析结果等。监测系统的井下通讯分机与地面接收主机的通讯采用rds传输技术，传输效率高，抗干扰能力强。
This system , as compared with point to point ' s early stage plc control ll system based on distributed control system ( dcs ) , have a large number of advantages , such as fewer i / o spots , smaller - sized plc , simpler plc ' s programming , less expenses for laying a lot of communication cable to control circuit , stronger antijamming and stronger adaptive control 该系统与早期的点对点式基于dcs的plc控制系统相比，具有减少i o点数、使plc小型化、简化plc的程序设计、节约铺设大量用于单回路控制的通信电缆的费用、抗干扰能力强、自适应能力强等优点。
