An optimal scheme is provided for the detection of moving objects observed in airborne SAR(Synthetic Aperture Radar) image.Along cross-range direction
the image data pass through a band-pass filter aiming at the frequency spectrum of the moving target and is corrected by subtracting the moving target quadratic phase error.Then
the same data pass through a band-pass filter aiming at the mirror frequency spectrum of the moving target and is corrected by adding the same quadratic phase.Both results are projected to time axis
and the moving target is detected by subtracting the two images’ energy.Combined with genetic algorithm
the effective parameter estimation and high detection speed are achieved.The experimental results verify the effectiveness of the method.
