Compound velocity measurement based on modulated frequency stepped radar

Millimeter waves modulated frequency stepped radar is a kind of important high-range-resolution radar,and motion compensation is the key technique to realize high range resolution.Three compound approaches for velocity measurement are presented and their feasibility is analyzed,based on which a feasible method is developed,and the parameter design and constraints about the complex signal are discussed.Simulation results indicate that the method can accomplish accurate estimation of the target velocity with good anti-noise performance while only a small amount of computation is needed.
