Abstract:

Aiming at the imaging problem of space target, a bistatic inverse synthetic aperture radar(ISAR) echo simulation method based on a twobody model is proposed. The method simulates the orbital characteristics of space target based on the twobody model. The threedimensional scatter model is built, the high speed movement and attitude stabilization are under consideration. Then the bistatic ISAR echo data is generated, and the determination method of target visible area relative to bistatic radar is given. Simulation results show that the error between the twobody model and real target orbit is small and the imaging results perfectly reflect the target attitude change. The echo simulation method based on the twobody model helps the accurate imaging of the space target and has an important guiding influence on imaging experiments.
