Due to the atmospheric turbulence. the motion trajectory of airborne very high resolution (VHR) synthetic aperture radars (SARs) is inevitably affected. which introduces range-variant range cell migration (RCM) and aperture-dependent azimuth phase error (APE). Both types of errors consequently result in defocused images. https://balboasurfandsstylers.shop/product-category/little-boys-trunks/
