Abstract


Synthetic aperture lidar (Synthetic aperture ladar, SAL) is a combination of Synthetic aperture radar (SAR) and the advantages of laser radar (ladar), can be all-weather, long distance, high resolution imaging surface or a wide range of space. Along with the development of related technologies, SAL has become an important developing direction of the imaging laser radar. This paper introduces the basic principle is side stripe pattern SAL imaging. According to the positive side stripe pattern characteristic of SAL radar raw data, the conventional SAR range doppler algorithm (RDA) and frequency variable scale algorithm (FSA) for transplantation. Select appropriate system parameters, using Matlab 7.1 software programming to realize the positive side stripe pattern SAL point target and the lattice imaging simulation, verify the feasibility and effectiveness of two kinds of imaging algorithm. In addition, according to the broadband signal phase error in the pulse compression effect, in this paper, the positive side stripe pattern SAL simulation study is made on several typical effect in the engineering, and explores the corresponding solution measures.
