摘　　要：本文采用D-S证据理论方法研究机载数字通信系统电磁环境适应性量化评估问题,并以某型直升机上的航管应答机为研究对象,对评估方法进行了验证,消除了以往评估中采用专家打分法等人为方法对评估对象进行评判时带来的主观因素影响,对系统电磁环境适应性的量化评估提供可靠依据。In this paper, D-S evidential theory was used to study the electromagnetic environment adaptability of communication systems in airborne with the ATC machine as the research object. It proved that this method was effective and it eliminated the subjective factors brought by the expert scoring method in the past evaluation. This method provides a reliable basis for evaluation of electromagnetic environment adaptability.
