| 1. | This thesis describes the key techniques of mode s ( selective ) , basic concept and its implementation . the respondent technology of mode s is based on the 24 bits address identifier of a plane , which could be used to detect the plane by the datalink , get the planes ’ property to identify , deal with the overlapping of several planes ’ replies 模式s的应答技术建立在对飞机的24位地址进行身份确认的基础上,能用更好的链路预测来探测飞机,而且能同时得到有助识别飞机的属性数据,能够处理多架飞机应答数据交叠的情况。 |
