摘要：
In order to solve the parameters estimation problem caused by the moving target with the micro motion in the GEOSAR model, a technique based on time-frequency distribution and least squares estimation is introduced. The model of micro motion part can be seen as a narrow band stochastic process, which is close to the reality of the motion. The method is used to estimate the parameters of the translation which is coupled with the micro motion. Simulation results indicate that the method can estimate the Doppler parameters of translation part efficiently.
