Optimum Time Interval Selection of ISAR Imaging of Ship Target

For maneuvering target exhibit roll, pitch and yaw motin, selecting the optimum imaging instant is very import for Rang-Instaneous-Doppler (RID) in ISAR imaging of these target. In this letter, a optimum imaging time interval selection method is proposed. The performance of proposed method is verified by comparing the result with the image produced by conventional method from the real data processing.
