In the past, the multiple reflection between armored target panels was ignored in the research of armored target radiation characteristics detection with passive millimeter wave.Therefore, we established the armored target radiation characteristics model with multiple reflection.Using ray tracing method, we deduced the calculation meth-od of multiple reflection and gave its calculation steps.The simulation results and their analysis verified preliminarily the correctness of multiple reflection and the necessity of its analysis.The results, we believe, provide a new analytical idea and theoretical basis for the study of millimeter wave radiation characteristics of armored tar-get.%针对以往毫米波被动探测装甲目标辐射特性研究中忽略了装甲目标面元之间辐射能量的多次反射问题，建立了装甲目标能量多次反射的辐射特性模型。采用射线跟踪方法从理论上推导了多次反射的计算方法并给出了计算步骤，仿真验证了多次反射的正确性及分析多次反射的必要性。为装甲目标的毫米波辐射特性研究提供了新的分析思路及理论依据。
