Research on the Phase Error Co mpensation in Synthetic Aperture Ladar by Using Optimization Algorithm
摘要
Abstract
In the field of remote sensing,the platform vibration is one of the important problems of synthetic aperture ladar (SAL).There is no efficient method in compensating the platform vibration of SAL currently.The platform vibration effects the phase of the received data.By analyzing the mechanism of platform vibration,the phase error caused by platform vibration can be described by polynomial function.The vibration is compensated by optimization algorithm which optimizes the polynomial coeffi-cients based on this conversion model.In optimization process,proper object function is needed and the phase of received data is compensated by optimization result,then the compensated data is compressed by matched filter.By simulation and experimental result,the conclusion is the better result of compression can be achieved after compensate the phase error by using the optimization algorithm.The research has offered candidate technology to platform vibration compensation.关键词
