Because of increasing SAR image resolution, the well-known classical statistical SAR image models sometimes do not fit to heterogeneous environment. In this paper, G0 model based CFAR detector is proposed to detect the vehicle targets in the heterogeneous ground environment. The G0 distribution model is known as suitable for various degree of homogeneity and is adopted as the statistical model in...
A new double-step fast CFAR scheme is proposed for multiple target detection in SAR images. The conventional multiple-cell based CFAR (MC-CFAR) detector is performed to find a potential target area. MC-CFAR carries out a quick search by which the CFAR sliding window is shifted by several cells for the reduced computational loads and it can also effectively reduce the small sized false alarm in the...
The type III band alignment of HgTe/CdTe superlattices leads to the interesting possibility of achieving very long wavelength infrared (VLWIR) (15 µm and longer) cutoff wavelengths with either normal (HgTe layer thickness less than about 70 Å for CdTe layer thickness of 50 Å) or inverted (HgTe thickness greater than about 70 Å) band structures. The inverted band structure superlattices promise even...
