N2 - Spaceborne dual-antenna uses satellite as platform, and the satellite center extends two antennas to both sides at the same time. The first antenna transmitting and receiving antenna while the second antenna is installed the other end. The antenna arm is used to form an interferometric baseline. Synthetic aperture radar (SAR) interferometry is achieved by using antennas at both ends of antenna arm transmitting and receiving signals. Comparing with SRTM system [1], [2], which extends a 60-meter antenna arm to form an interference baseline for interferometry, the new system will have better performance. But during the flight, the attitude adjustment of the engine will cause the antenna mast motion, which will affect the SAR imaging and interferometry. The relatively regular slow motion can be compensated, but the fast motion is difficult to measure because of randomness. So we should analysis the effect of fast antenna mast motion in this system. In this paper, the amplitude and frequency threshold model of the antenna fast mast motion in dual-antenna SAR system is proposed by theoretical derivation. At the same time, the accuracy of the theoretical analysis is verified by the simulation experiment of the whole process, which provides theoretical support for design of dual-antenna system.
