The Range-Instantaneous Doppler Imaging method to maneuvering Targets

摘要

Range-Doppler imaging, a basic method used in the inverse synthetic aperture radar (ISAR), is based on the uniform rotation model of a target. The rotation velocity and axis of maneuvering targets, often vary with time. The trditional imaging method may blur the target image and even make it beyond recognition. A concept is presented for range-instantaneous Doppler imaging and the corresponding imaging method that can improve the image quality of most maneuvering aircrafts. The resulting images of real data show that this method is effective.
