N2 - A clear ISAR image could not be acquired by conventional Range-Doppler (RD) method due to the non-uniformly of angular motion of ships as scatterers caused by the sea save, thus the method for solving the problem by applying Range-Instantaneous Doppler (RID) methods are used. However, though each scatterer could be resolved from the echoes, such methods suffer from heavy calculation burden due to the searching process. An ISAR imaging method of parameter estimation based on optimal imaging period is proposed. The method chooses optimal data from all received echoes, and then achieves imaging by parameter estimation according to each range bin's Doppler data. The effects of choosing imaging period on parameter estimation is analyzed, and the steps of accomplishing the proposed method are developed. The result of estimation on real data manifests that better ISAR image can be acquired by applying the method proposed.
