Space target recognition method based on Dynamic template matching of HRRP

摘要

In view of this problem of strong correlation between the existing recognition template training method and the recognition scene,the requirement of the prior knowledge of scene is higher, and the recognition is not suitable A method of spatial target recognition based on dynamic template matching is proposed.Firstly, the omnidirectional static data attitude sensitivity of the target is analyzed, and the recognition threshold is given by the minimum K-L distance In the recognition process, the Line of sight angle of the target is estimated by the radial length of the one-dimensional range image,The line of sight angle distribution in the accumulation window is extracted,Extracting the static data from the same line of sight to generate the identification template in real time, and matching the template with the test data to be identified, and then complete the target recognition by recognizing the threshold.
