The railway station track parking vehicle detection method comprises the steps that a leaky coaxial cable is arranged on a station track, slotted holes are periodically formed in the leaky coaxial cable, and one end of the leaky coaxial cable is connected with a guided wave radar; the guided wave radar transmits a positioning pulse to the leaky coaxial cable, the positioning pulse radiates outwards through a slotted hole of the leaky coaxial cable, is reflected to form a plurality of echo pulses after encountering the bottom of a station track staying vehicle, is coupled into the leaky coaxial cable through the slotted hole, and is received by the guided wave radar; and the guided wave radar calculates the positions of the two ends of the station track parking vehicle according to the time delay of a plurality of echo pulses formed by the positioning pulse through different slotted holes relative to the emitted positioning pulse. The method has the beneficial effects that according to the detection method, the distance is calculated according to the delay of a plurality of echo pulses formed by the positioning pulse through different slot holes relative to the emitted positioning pulse, and multi-target positioning is realized; the intensity of the echo signal is increased by adopting a multi-pulse space accumulation or time accumulation mode, and the signal-to-noise ratio of the echo signal is improved, so that the guided wave radar can identify the time delay of the echo pulse more accurately.
本发明的铁路股道停留车检测方法,包括在股道上设置漏缆,漏缆上周期性的开有槽孔,漏缆一端连接导波雷达;导波雷达向漏缆发射定位脉冲,定位脉冲经由漏缆的槽孔向外辐射,遇到股道停留车底部后被反射形成多个回波脉冲,通过槽孔耦合进漏缆,被导波雷达接收;导波雷达根据定位脉冲经由不同槽孔形成的多个回波脉冲相对于发射的定位脉冲的延时,计算出股道停留车两端的位置。本发明的有益效果:本发明的检测方法根据定位脉冲经由不同槽孔形成的多个回波脉冲相对于发射的定位脉冲的延时计算距离,实现了多目标的定位;采用多脉冲空间累积或时间累积的方式增加回波信号的强度,提高了回波信号的信噪比,使得导波雷达能更准确地辨识回波脉冲的延时。
