With the trend of emphasis on concealable attack and forcible ruin to military supporting systems , passive locating methods can be seen as an important direction to the development of locating methods and perfection to existing locating systems . passive locating methods have the merits of far distance , concealable receiving and low probability to be detected , compared to active locating methods . so , passive locating system can help to improve viability and battle effectiveness of the whole system in the electronic war environment 在越来越强调军事支援系统隐蔽攻击和硬杀伤的趋势下，采用被动方式工作的无源定位方法作为定位方法发展的一个重要方向和对现有定位系统的完善，较有源定位方法具有作用距离远、隐蔽接收、不易被对方发觉的优点，对于提高系统在电子战环境下的生存能力和作战能力具有重要作用，同时在航海、航空、宇航、侦察、测控、救援和地球物理学研究中有着广阔的应用前景。
Modern warfare relies more and more on the use of radar sensors in a complex electronic environment , which include deliberate sophisticated countenrieasures . since the effectiveness of the radar and radar electronic warfare system , both equipment performance and tactics effectiveness are difficult to define and even more difficult to measure or predict , computer simulation become an important way to test and evaluate its effectiveness 在复杂电磁环境下的雷达及雷达电子战是现代高科技战争的主要特点之一，但是雷达电子战系统在研制和使用过程中对雷达电子战设备性能预测和系统作战效能评定是非常复杂和困难的，而且目前对雷达电子战设备性能和作战效能进行评估的技术手段和平台环境还比较缺乏。
If any of the asco member countries were invaded by country or countries outside this area , being invited by lawful government ( s ) of the invaded , with decision and arrangements made by the board of executors by two - thirds majority including china and russia , all member countries must provide the invaded countries with necessary forces , money and military materials and , together with asa forces , run to their rescue 在发生成员国遭受外部武装入侵的情况之下，经受侵略国合法政府请求，并经亚洲安全合作组织理事会以包括中国和俄罗斯在内的三分之二多数票做出决定和安排，各成员国得提供必要的军队、经费和作战物资，与亚安军各部队一道，共同为受侵略国提供援助。
In addition , the general headquarters / departments organized successive studies and exercises of communications and command at the joint operational level , training of landing and mountain operations , and research on methods of joint penetration operations , and explored the features and patterns of integrated network and electronic warfare 总部机关还相继组织了联合战役通讯指挥研练、登陆和山地作战训练以及联合突防战法研讨，并探索了网电一体战的特点和作战样式。
