According to the method for identifying and confirming the side lobe of the transponder, side lobe processing is included in a whole vehicle-mounted train control system, the lobe envelope width of the transponder is calculated by combining train speed information, and the side lobe is identified according to the width difference between the side lobe envelope and the main lobe envelope; meanwhile, the side lobes are further confirmed according to the distribution characteristics of the side lobes and the main lobes, and after confirmation is completed, transponder information is reported to a rear-stage vehicle-mounted train control system. The method has the advantages that the BTM end confirms the side lobes of the transponder through recognition, the train positioning precision of the train-mounted train control system end is improved, and meanwhile the accuracy and reliability of side lobe recognition of the system can be further improved through reconfirmation of the side lobes by the train-mounted train control system end.
本发明的应答器旁瓣识别与确认的方法,将旁瓣处理纳入整个车载列控系统中,结合列车速度信息,计算出应答器的波瓣包络宽度,并根据旁瓣包络与主瓣包络的宽度差异,识别出旁瓣;同时依据旁瓣与主瓣的分布特征对旁瓣进一步确认,确认完成后,再向后级车载列控系统上报应答器信息。本发明带来如下技术效果:BTM端分别通过识别确认应答器旁瓣,提升车载列控系统端列车定位精度,同时通过车载列控系统端对旁瓣的再确认能够进一步提高系统对旁瓣识别的准确性、可靠性。
