A Study on Airborne High Squint Radar Imaging Algorithm
摘要
Abstract
Based on high aquint SAR imaging of the spatial geometry models and the characteristics of echo data, the aolution is processed to the linear frequency modulation in distance and azimuth. It corrected the walking distance and range bending in the time domain. And then the separately Fourier transform of azimuth and distance make the signal to the correct position. The algorithm started from the real-time imaging, based on the resolution of the required conditions, minimize the volume and complexity of operations. Because of the high-order phase compensation algorithm has little effect by the oblique angle of entry, it can accurately handle large distance walking and bending. Point target simulation and measured data imapng results demonstrate the feasibility of the algorithm.关键词
