摘要: 针对JTIDS的信息传输时间延迟问题,分析JTIDS中两点之间的3种信息传输过程(直接信息传输、通过中继站信息传输、高优先级信息传输),将信息传输过程抽象为排队论模型,给出时间延迟的求解方法,分析预警机在一定的时隙分配方案下传输各类信息的传输时间延迟。分析结果表明,JTIDS系统能够依据传输信息的种类,较好地控制信息传输时间延迟,满足作战需求。

Abstract: This paper focuses on the time delay of JTIDS. Three message transmission processes, direct message transmission, message transmission through relay and prior message transmission are analyzed and modeled as queue theory models. Methods to calculate the time delay are proposed. It analyzes the time delay of early warning plane under certain time slot allocation method. Results show that, JTIDS meets the operation needs by controlling the time delay with respect to the category of the message.

Key words: datalink, time delay, queue theory, JTIDS
