采用常规方法建立的雷达与干扰信号级仿真系统, 存在系统难以扩展、仿真效率低的问题。针对该问题, 从3个方面提出了改进方法: 一是雷达和干扰机之间交互内容使用各自发射端的信号, 代替到达对方接收机的信号; 二是雷达提前一个周期公布发射信号, 并延后一个周期处理信号; 三是相互间传递信号描述字而非数字信号。然后, 分析了仿真步长、时间前瞻量的参数设置问题。最后, 通过仿真实验, 验证了改进方法的有效性。改进方法减少了雷达与干扰机之间的依赖性和交互次数, 节省了网络开销, 有利于提高系统的可扩展性和仿真效率。

In simulation systems of radar and jammer established with conventional methods, the systems are often difficult to expand and have low efficiency due to the close coupling. An improved method is proposed to solve this problem from three aspects. Firstly, the signals transmitted from the radar and jammer, instead of the received signals, are used as the signals transferred between them. Secondly, the radar publishes the transmitting signals one period earlier than the event time stamp and postpones the processing of signal for one period. Thirdly, the signal descriptors, rather than the digital signals, are transferred between radar and jammer. An analysis is made to the parameter setting of simulation time step and lookahead time. The effectiveness of the improved method has been verified by simulation experiment. The proposed method decreases the information dependency between radar and jammer, reduces the times of data interaction between them, saves the network overhead and improves the expandability and efficiency of the simulation system.
