    • The Phase Gradient Autofocus Algorithm with Range Dependent Stripmap SAR

    • The Phase Gradient Autofocus Algorithm with Range Dependent Stripmap SAR

    • Synthetic aperture radar, SAR, stripmap SAR, spot light SAR, phase gradient auto focus, auto focus algorithms, maximum likelihood phase gradient algorithm

    • The Phase Gradient Autofocus (PGA) algorithm is widely used in spotlight mode SAR for motion compensation. The Maximum Likelihood PGA (ML PGA) algorithm has been shown to be a superior autofocus method. The PGA is restricted to high altitude...

    • Improving Electromagnetic Bias Estimates

    • EM bias, electromagnetic bias, physical optics, backscatter models, mean sea level, altimeter

    • The electromagnetic (EM) bias is the largest source of error in the TOPEX/Poseidon and Jason-1 satellite sea surface height (SSH) estimates. Due to incomplete understanding of the physical processes which cause the bias, current operational...
