Abstract
A method and system for enhancing a radar image provides for application of digital imaging processing techniques to a range-Doppler image produced by a radar system. The application of digital processing techniques includes a 2-D band-pass filter including a smoothing filter followed by a differentiating filter applied to the image. A constraint on concavity is placed upon the resultant 2-D band-pass filtered image to create a mask. The application of this mask to the original image results in an enhanced range-Doppler image with increased resolution.
