Micro-Doppler analysis and imaging of air-planes with rotating parts

摘要：

In ISAR imaging of air-planes with rotating parts,the micro-DoppIer phenomenon induced by the rotors will generate side-bands about the rigid body image. This paper derives the imaging model and analyzes the micro-Doppler of rotors. Then,a method for microDoppler separation based on low chirp rate matching is proposed.Meanwhile,an algorithm for scaling the 2D imaging of rigid body is presented,based on the complex-valued back-projection algorithm.Similarly,ISAR imaging of the rotating rotors can be obtained through the same algorithm.Finally,images from the rigid body and the rotating rotors are merged together to obtain a full image of the air-plane. The validity of the proposed algorithms has been proved by simulations.
