摘要
The time synchronization problems of bistatic ISAR using indirect time synchronization continuous sampling mode is studied. Firstly, the characteristics of the time system in bistatic ISAR are analyzed. Then, the time model of bistatic ISAR using indirect time synchronization continuous sampling mode is established. The model depicts the time system of bistatic ISAR using fast time, slow time and time synchronization error respectively. Based on the time model, the effect of continuous sampling on bistatic ISAR imaging is discussed. The influences of the non-ideal clock to the echo phase and to the ISAR imaging is also analyzed. Finally, the simulations of bistatic ISAR imaging with different time synchronization mode are carried out. The simulations indicate that the indirect synchronization continuous sampling mode has little adverse effect on ISAR imaging, and is highly tolerant to the non-ideal clock. It is proved that such synchronization mode can solve the time synchronization problem of bistatic ISAR effectively.
