分析机载数据中继系统的组成和机载天线控制特性，使用真实数据接收机解调并输出数据，使用软件模拟机载天线运动和波束特性，完成半实物仿真方式的机载数据中继系统模拟器的设计。通过高速以太网和RS-485现场总线的两级控制网络的方法，两台嵌入式计算机协同完成仿真任务，中继模拟器具备单独节点可操作能力和快速实时响应特性，该方法在复杂设备的仿真中具有明显优点。中继模拟器经过了可靠性、维修性、测试性、保障性评估试验，在实际使用中效果良好。
Abstract:
Based on analysis of an air borne data-relay system （ADRS） and its antenna control characterisTIcs，an ADRS is designed，using a real data receiver to demodulate and output data，and software to simulate the characterisTIcs of antenna moTIon and wave beam. Two embedded computers are cooperated to finish the simulaTIon task，with a fast Ethernet network and RS-485 field bus. The ADRS simulator features the ability of operation at every single node and fast response. It is a hardware-in-loop simulator and pass test of reliability，maintainability，testability，supportability and works well in real usages.
