| Abstract: | Based on the establishment and analysis of signal model for ship target of the shore-based bistatic ISAR,the movement of the ship was analyzed by utilizing the equivalent radar LOS of bistatic radar.The result of the kinetic analysis was used to select the observation data segment and the mixed view of ship was obtained.By using the ship sub-image sequence generated from successive data segments,the Doppler spreads and vertical rotational component were estimated.Then,the imaging timlines for ship side view... |
