双基地合成孔径雷达技术
|
Abstract:
双基地合成孔径雷达（SAR）系统的发射和接收装置承载于不同的平台，系统配置灵活多样，接收装置适装性强，电磁隐蔽性好，不仅能实现对地侧视成像，还能够实现前视成像，是SAR技术新的发展方向之一。由于双基SAR在几何构型、工作模式、分辨特性和应用领域等方面与传统单基SAR存在明显差异，在成像理论、系统组成、收发同步、参数估计、运动补偿、成像处理和试验验证等方面，双基地SAR也存在一系列新的理论、方法和技术问题。近年来，国际雷达界对这些问题开展了广泛深入的研究工作，获得了一些新的认识。该文拟从空间关系和物理概念角度，论述双基SAR成像原理、构型分类、应用特点、系统组成、性能参数、研究现状和发展趋势，简要分析双基SAR与单基SAR的异同，并对双基SAR未来的发展趋势做简要的展望。
