雷达间的电磁兼容性判决

Estimation and Determination of Electromagnetic Compatibility between Radars

通过对雷达信号(或干扰)处理过程的分析,对发现概率和虚警概率的定义作了合理的扩展,使二者可以直接用于雷达间的电磁兼容判定,并在此基础上建立了雷达间电磁兼容判决模型。这种基于经典雷达信号检测理论的模型能客观、真实地反映出雷达间的干扰情况,并且可以应用在雷达间电磁兼容性预测模型中。

The processing of signal （or interference） in radar system is described in this article, and the extended definition of discovery probability （DP） and false alarm probability （FAP） is made based on the need of the problem. The DP and FAP are used in determining EMC between radars directly because of the definition extension, and then the EMC determination model is established. This model based on the theory of signal detection can illuminate the condition of interference between radars realistically and objectively. Also, it can be used in EMC-between-radars forecast model.
