Phase autofocus algorithmPGA algorithmThe phase gradient autofocus algorithm (PGA) is widely used in radar imaging due to its ability to achieve high accuracy estimation of phase error. However, in inverse synthetic aperture radar (ISAR) imaging, the target usually occupies continuous range bins and...

For a light field, the wavefront determines the axial variation of the intensity in the direction of propagation. Specifically, there is a quantitative relationship between the gradient and curvature of the phase and the axial differentiation of intensity, the so-called transport of intensity equation...
After desalting, the peak fractions were loaded onto a HiTrap Q column (GE Healthcare) and washed sequentially with lysis buffer at different salt concentrations (50 mM KCl; 87.5 mM KCl; 200 mM KCl), before final fractions were eluted in lysis buffer using a salt gradient from 200...
Proteins were separated by SDS-PAGE using Bis-Tris 4–12% Bolt gradient gels in MES or MOPS buffers in a Mini Gel Tank (Thermo Fisher). Western blot analyses were performed using a wet transfer Criterion Blotter (BioRad) in MOPS/20% ethanol transfer buffer using Immobilon-FL PVDF membranes...
And then,the strip phase gradient autofocus(PGA) algorithm is ameliorated. 首先建立了适合机载UWB SAR成像几何的相位误差模型,并分析了其特点;然后针对模型特点,对条带式相位梯度自聚焦算法作出改进,同时提出一种基于空不变因子估计的加权相位梯度自聚焦算法。 3. A new phase gradient autofocus(PGA) algorithm...
Phase Gradient Autofocus(PGAReal-time processingAdaptiveThe Phase Gradient Autofocus(PGA) algorithm can remove the high order phase error effectively,which is of great significance to get high resolution images in real-time processing. While PGA usually needs iteration, which necessitates long working ...
