| Popis: |
Two moving target detection methods in a given synthetic aperture radar (SAR) imagery are proposed based on the theory of SAR imaging. The methods are performed by using the phase information of the image patch by patch. First, an average Doppler spectrum is achieved from the stationary parts in the image and used as a standard one in the successive computations. Then an average Doppler spectrum of a selected image is computed and used to detect moving targets with random directions by correlation and normalized difference computation. Finally, the effectiveness and practicability are validated by theoretical and field data. |
