Abstract
Synthetic Aperture Radar(SAR) is a high-resolution imaging radar,while the matrix transpose is a critical step in the real-time signal processing of SAR imaging, the efficiency of matrix transpose greatly influence the performance of the signal processing system.Some popular methods can be utilized to achieve the matrix transpose, such as in row out column (IROC) or in column out row(ICOR),two-page or three-page transpose method,etc.However,these methods are not very effi-cient.In this paper, a new matrix transpose method is proposed based on the existing matrix transpose methods.An actual hardware platform is used for real-time imaging process using the new matrix transpose method described in this paper. The efficiency of matrix transpose is 78% with the entire SAR imaging runtime of 10 seconds.Experimental result demonstrates that the method proposed is efficient for solving the matrix transpose problem.关键词
