摘要

The Continuously Varying Pulse Repetition Interval (CVPRI) technique is an effective method to acquire Synthetic Aperture Radar (SAR) echo data with significant Range Cell Migration (RCM). The non-uniformity of echo data along the azimuth direction is the primary problem faced in the imaging processing caused by the CVPRI. This paper is focused on the reconstruction of Non-Uniformly Sampled (NUS) signal based on the CVPRI. Then, a modified imaging algorithm combined with the azimuth Non-Uniform Sinc Interpolation (NSI) method is proposed to achieve the NUS echo data focusing. Simulations are conducted to validate the effectiveness of the novel reconstruction method as well as the modified imaging algorithm.
