摘　　要：装备射频系统的兼容性是确保装备生存力和战斗力的一项重要综合能力。由于射频兼容涉及众多射频设备,交联关系复杂,对其试验考核一直是装备综合能力试验的重点和难点。基于此,提出了一种机载综合射频系统兼容能力试验方法。首先介绍了综合射频系统兼容工作的基本原理,作为兼容能力试验方法设计的基础。进一步提出了基于正交法的射频兼容能力试验内容设计方法,从射频设备、射频设备工作模式进行了多层次的正交矩阵设计,并给出了试验设计结果的一般筛选原则。在此基础上,从功能和性能两个方面研究给出了射频兼容能力的评估准则,进而构建了一套射频兼容能力试验设计与评估方法。基于研究方法以某航空装备平台为例进行了案例分析,结果表明本文方法可以有效地支持对机载综合射频系统兼容能力的试验内容设计和兼容能力评估。It is an important comprehensive ability of radio frequency(RF) systems compatibility to ensure equipment survivability and combat effectiveness. Because of numerous RF equipments and complex cross-linking relationships, it has always been the focus and difficulty of the test and assessment of RF compatibility for equipment comprehensive capability test. Thus, a compatibility test method of airborne integrated RF systems was proposed. Firstly, the basic principle of compatibility of integrated RF system was introduced as the basis for the design of compatibility test method. Furthermore, the design method of RF compatibility test content based on orthogonal method was proposed. The multi-level orthogonal matrix design was carried out from the working mode and RF equipment, and the general screening principle of test design results was given. On this basis, the evaluation criteria of RF compatibility were given from two aspects of function and performance. At last, the RF compatibility of an aviation equipment was analyzed. The results show that our method can effectively support the experimental design of the compatibility of integrated RF system.
