ABSTRACT

Phase synchronization error is one of the major problems that must be considered in distributed MIMO SAR(synthetic aperture radar, SAR) systems. Azimuth ambiguity eliminating is an important step in signal processing process, used to eliminate the azimuth spectrum ambiguity caused by low PRF. To analyze the effect caused by phase synchronization error, this paper presents the signal model under the distributed MIMO SAR system, establishes a phase synchronization error signal model, and derives the influence of phase synchronization error on signal processing. Then simulated the phase synchronization error on signal doppler ambiguity eliminating. This paper is of great significance for studying the influence of phase synchronization error on system performance under the distributed MIMO SAR system, and makes a contribution on subsequent research in error compensation methods
