| description | The invention discloses a high-dynamic railway environment radar sensing method based on a fixed grid, and the method comprises the steps: firstly, employing a millimeter-wave radar denoising method based on the fixed grid, removing the flash noise generated in a millimeter-wave radar sensing process, and then carrying out the recognition of the effective target according to the obtained speed, acceleration, position coordinates and other information of the effective target. The effective targets are divided into static targets and dynamic targets through a clustering algorithm, and finally, according to a radar target early warning grade classification table established in advance, early warning grade discrimination is carried out on the effective targets. The method is good in stability, can adapt to a high-dynamic railway environment, effectively removes the flash noise, and improves the target recognition accuracy of the millimeter wave radar.
