摘　　要：阐述SUBSET-036应答器传输系统技术规范V3.0.0和V3.1.0版本对BTM带内抗干扰性能的测试要求;采集并分析动车组动态运行试验中BTM接收到的带内干扰信号;通过综合比较不同信号解调算法对BTM设备译码质量和抗干扰性能的影响,提出通过优化信号解调算法提高BTM带内抗干扰性能,以及采用天线屏蔽、电缆屏蔽等物理措施尽量减小干扰信号的强度。The test requirements of the two versions of SUBSET-036 V3.0.0 and V3.1.0 standards for BTM in-band anti-interference performance are introduced firstly,and the in-band interference signal received by BTM in train dynamic test is collected and analysed secondly.By comprehensively comparing the influence of different signal demodulation algorithms on the decoding quality and anti-interference performance of BTM equipment,it is proposed to improve the anti-interference performance of BTM in the band by optimizing the signal demodulation algorithm,and to minimize the intensity of interference signals by adopting physical measures such as antenna shielding and cable shielding.
