Azimuth Signal Pr ocessing for Near-Space High-Resolution and Wide-Swath SAR Imaging

摘要：

Near-space defined as the space region between 20km and 100km can offer many capabilities that are not accessible for satellites and airplanes.By placing transmitter/receiver inside near-space platforms,many functions that are currently performed with satellites or airplanes could be performed much more cheaply and with greater operational unity.It appears that near-space can provide a satisfied solution to highresolution and wide-swath (HRWS) SAR imaging.Inspired by these promising advantages,this paper describes the concept of near-space HRWS SAR for remote sensing applications.A multiple-beam based azimuth ambiguity suppression technique is presented.The system concepts,signal models,and correspondding azimuth signal processing algorithms are provided.An example near-space HRWS SAR system is conceptually designed.
