摘　　要：接收机的非线性效应严重影响武器装备的正常工作,是目前战场电磁兼容预测分析重点研究的问题之一。由于接收机的非线性来源具有一定的复杂性,无法直接进行电路分析,因此需要建立相应的行为级模型进行研究。因此,综述非线性行为级建模的主流分析方法,评述各方法在非线性建模中应用的优点和不足,重点论述了离散非线性分析技术的高阶非线性行为级建模过程,指出了接收机非线性建模需要进一步研究的问题。Nonlinear effect of the receiver seriously affects the normal operation of weapons and equipments,and is one of the key issues in the prediction analysis of current battlefield electromagnetic compatibility.Due to complexity of the receiver’s nonlinear source,it is impossible to perform the direct circuit analysis,so it is necessary to establish the corresponding behavior level model for research.Therefore,the mainstream analysis methods of nonlinear behavioral level modeling are reviewed,he advantages and disadvantages of each method in nonlinear modeling summarized,the high-order nonlinear behavioral level modeling process of discrete nonlinear analysis technology emphasized,and the problem that the nonlinear modeling of receiver needs further study pointed out.
