Abstract
Micro-Doppler effect has been referred to as the unique characteristic of radar targets for targets classification and recognition. The application of interferometric inverse synthetic aperture radar (InISAR) imaging for low-altitude targets based on linear frequency modulated continuous wave (LFMCW) radar is studied in this paper. Taking three kinds of helicopters as example, the echoes of targets are modeled and the method for echoes separation of scatterers from rotation parts and main body is presented. Then taking the interferometric processing to the echoes, three-dimensional image of the target can be obtained. By using the extracted micro-motion parameters, the classification of the three kinds of helicopters is accomplished.
