A method for recovering maneuver targets spectra based on the algorithm of decontaminating ionospheric slow phase-path disturbance

Both ionospheric slow phase-path disturbance and targets' maneuver will make the targets' echoes broaden in HF radar. Although their mechanism to spread the spectra is different, they are consistent on the view of the phase of targets' echoes. Using the algorithm of ionospheric disturbance decontamination which has been successfully applied in practice, a method for recovering maneuver targets spectra has been presented in this paper. Results of experimental data of HF radar and meter-wave radar verify the correctness of such process. And they also show that the algorithm can effectively improve the quality of the targets spectra to improve the radar target detection and tracking performance.
