| Abstract: | The effect of target motion on a synthetic range profile produced by modulated frequency stepped radar is analyzed,a method for the estimation of target motion parameter with the least burst error principle is analyzed.This method is adopted by modulated frequency stepped radar to estimate the target velocity and make compensation for the range profile.Theoretic analysis and simulation results indicate that the method is feasible and is capable of achieving accurate estimation with efficient computation and good anti-noise performance. |
