Abstract

Based on time-frequency analysis, an auto-adaptive accumulation ISAR imaging algorithm is proposed in this paper, which is especially suitable for complex motion target imaging. This new algorithm adaptively adjusts its accumulating scope by means of the echo correlation coefficient threshold and eliminates the strong interference cross-term by means of entropy principle. Validity of the proposed algorithm is verified by real ISAR data imaging
