Micro-Doppler Shift Compensation for Ballistic Targets Based on Residual Network ResNet50

During the mid-flight of a ballistic target, there are two types of motions: high-speed translational motion and micro-motion. Since the translational motion causes the Doppler curve to be shifted and tilted, the translational component needs to be compensated. In this paper, a new micro-Doppler shift compensation method for ballistic targets based on Residual Network ResNet50 is proposed. The micro-Doppler compensation is converted into a regression analysis of radial motion parameters, and the regression analysis is carried out using ResNet50. According to the results of simulation experiments, the algorithm can realize the compensation of translational components.
