摘　　要：介绍了接收机非线性产生的原因及其对接收机造成的影响。讨论了目前几种接收机非线性表示方法在复杂电磁环境下进行接收机干扰分析时存在的局限性。提出了利用接收机非线性项系数直接进行接收机非线性性能表示,并给出了进行接收机非线性项系数测试和计算的方法。利用该方法对一台接收机进行了具体的测试和计算,根据计算结果进行接收机受干扰仿真分析,与实测能够较好地吻合。The causes of receiver non-linearity and its effect on receiver are introduced.The limitation of the current receiver non-linearity representations in analyzing receiver interference in complex electromagnetism condition is discussed.This paper presents a method of using receiver non-linearity term coefficient to represent receiver non-linearity.And it puts forward a test and calculation method of receiver non-linearity term coefficient.The test and calculation for a receiver is performed by using this method.The simulation result analysis shows the calculation result can accord with the actual measurement result.
