摘要：
To obtain the inverse synthetic aperture radar image of a target, certain rotation angles of the target with respect to radar line of sight during the coherent integration interval are required, migration of scatterers will take place. Actually, scatterer migration through resolution cells (MTRC) will happen inevitably in high-resolution radar imaging, which will result in image resolution degradation. Scatterer MTRC is discussed, then a simple and an efficient algorithm, the MTRC compensation algorithm (MTRCCA), is proposed to compensate MTRC. The relationship between the MTRCCA, range-doppler and polar formatting algorithms is also discussed. ISAR images from simulated and real data measured in a microwave anechoic chamber are presented to validate the proposed algorithm.
