Low-speed small target trajectory detection method based on multi-frame coloring under reverberation background

According to the low-speed small target trajectory detection method based on multi-frame coloring under the reverberation background, a GMM method or an RPCA method is adopted, and then a splicing tensor is obtained in a direct splicing mode or a large splicing mode. And coloring the spliced tensor to obtain a color track detection result. According to the method, the continuous trajectory of the target is detected by utilizing the inter-frame position migration continuity of the low-speed small target, the inter-frame position randomness of the dynamic reverberation and the inter-frame position invariance of the static reverberation. In the detection result, the static reverberation and the dynamic reverberation are represented by a single color, and the continuous track of the target is represented by a color gradient strip. The basic principle and the implementation scheme of the invention are verified by a synthetic data processing result, and the result shows that compared with the traditional method, th
