Stripmap phase gradient autofocus(SPGA) algorithm which may be used for broad band stripmap synthetic aperture sonar is proposed. 提出了一种适用于宽带条带式合成孔径声纳的相位梯度自聚焦(SPGA,stripmap phase gradient autofocus)算法。4) synthetic aperture sonar 合成孔径声呐 1. A frequency domain da...
With a global high-quality input, the residual range-variant phase errors can be retrieved precisely utilizing a center-to-edge local maximum-likelihood weighted phase gradient autofocus kernel at last. Experiments on real VHR airborne stripmap SAR data are performed to demonstrate the robustness of...
