摘要
针对雷达与雷达之间的电磁干扰问题，建立了发射源模型、传输通道模型、接受器模型和天线之间的耦合模型，给出了雷达系统的干扰预测方程。据此模型可方便地编制预测分析软件，由给定的雷达参数和工作环境参数计算出干扰噪声比；在雷达天线处于扫描工作状态时可得到干扰概率，同时提出了一个便于计算干扰概率的简化模型，可快速有效地对雷达之间的电磁干扰状况进行预测分析。
The mathematics models used in the prediction of electromagnetic interference between radar systems are obtained, in which the interference prediction equations are given. The radiated characteristics of emission device, transmission paths including two different terrains, receiver response and coupling between antennas are introduced. The interference probability is studied as radar antennas scan. The prediction programs can be compiled by the models.
