Abstract Jammer motion brings trouble to the dual-channel cancellation, but the good result is restricted to a limited range. The rotation motion of a jammer is periodic, the effect of rotating jammer on InSAR dual-channel cancellation is studied in this paper. Since the rotating arm is too long to put into practice, an alternative method using multi-antenna jammer is presented, the antennas emit interference signal on a time division basis. Simulation result shows that the proposed method is effective.
