This paper proposes a Gabor feature based ionospheric clutter region extraction method in RD map for its good performance of picking up the orientation information from such clutter in a Range-Doppler map. The better performance of the proposed method is shown by comparing with the statistical information based and adaptive threshold based methods. Such results can be used for ionospheric clutter...
When targets fall in different types of clutter and noise background in High Frequency Surface Wave Radar (HFSWR), uniform detection algorithms always result in poor detection and tracking performances. To solve the problem, two methods are proposed in this paper by extracting the background features according to the probability distribution and the image characteristic of the spectrum map. The first...
