In the paper, the proposed multicarrier radar waveform which alternates the direction of frequency sweep between successive LFM signals has excellent orthogonality. Then the processing of the multicarrier waveform echo when the target is still or moving are detailed discussed as well as some key problem. Based on the preliminary velocity estimation by the especial relationship between subcarrier and Doppler shift and the minimum entropy estimation, the combining velocity compensation method is advanced. The simulation results and performance analysis show that method has fewer computation load and the stability.
