It is the basis of realization ship recognition to accurately extract geometric parameters of the ship target in synthetic aperture radar (SAR) images. Due to the unique SAR imaging mechanism, speckle noise, azimuth ambiguity and side lobe effect seriously impact on geometric parameter estimation of the ship target. Therefore, a method is presented to extract geometric parameters of the ship based...
The orthogonal frequency division multiplexing (OFDM) MIMO SAR is the combination of sub-aperture technique and sub-band technique to achieve high azimuth resolution, high range resolution, and wide swath simultaneously. However, the interference of the sub-bands and the channel errors (channel mismatches), like constant phase error, amplitude error, and sampling delay error of the fast time, have...
In this paper, the main problems of fusion techniques of airborne SAR and optical images are discussed. First, the regions of interest for target candidates in each mono-source data are independently segmented, and then the fusion is processed during the decision stage. A novel detection method of fusion images of targets which is based on "3S" technology is proposed. The experimental results...
