Abstract

Radar plays an important role in urban public transit system, so it is of great significance to ensure the safe operation of High-speed rail. Radar communication integration technology has the characteristics of high efficiency and low energy consumption, it can improve communication quality, speed up transmission efficiency and improve detection accuracy. Firstly, this paper introduces the running scene of High-speed rail, and puts forward that radar communication integration technology has a broad application space in High-speed rail. Then it introduces radar communication integration technology, and the research status, advantages and development prospects of radar communication integration technology based on linear frequency modulation(LFM). Finally, it is proposed that obstacle detection technology is one of the difficulties to ensure the safe operation of High-speed rail. Radar integration technology can be effectively applied to train obstacle detection, which is an important technical support for improving service quality and speeding up the intelligent construction of High-speed rail in the future.
