Accelerating targets induce chirped signals in the radar backscatter signal which cannot be efficiently detected by the direct application of the traditional Fourier transform. In this report, we propose a method based on a de-chirping factor and the Fourier transform for detecting accelerating targets in land or sea clutter environments. The method is found to be simple, yet highly effective. The results are demonstrated with both simulated and real data.
