摘要：

To solve the problem of mutual superposition and interference of multi-target micro-Doppler in midcourse, a method based on modified ant colony optimisation (ACO) is proposed. On the basis of building 3D time-frequency map, pheromone on each spot in the workspace can be updated, according to the changing rule of micro-Doppler. The pheromone leads ant to seek for required optimal micro-Doppler path gradually; thus single micro-Doppler curve corresponding to each scattering point can be separated. Simulation results indicate that the proposed method can overcome the coupling between micro-Doppler of different scattering point and the influence of background noise better, and implement effective separation of multi-target.
