Abstract The imaging method on low-altitude target in strong ground clutter is presented. The identical amount of stretching time-delay with the adjoined echoes is applied in the signal stretching process, and then the ground clutter is filtered through the one-order canceller. Furthermore the target’s motion parameters can be accurately estimated by the narrow pulse signals on the constant carrier, so the motion compensation can be achieved. After the theoretical analysis, the validity is proven by simulation results finally.
