ISAR Imaging with LFM waveforms

This thesis demonstrates a technique involving Linear Frequency Modulation (LFM) waveform and Inverse Synthetic Aperture Radar (ISAR) processing to develop two-dimensional radar images of a missile target. The processing is combination of two high-resolution processes: development of a high-range resolution (HRR) profile in down range using LFM waveform, and the development of high-resolution profile in cross-range using the ISAR technique. With these two techniques complementing each other, images of targets´ dominant scatterers can be extracted, processed and displayed. This method is a practical method to process LFM radar data, in order to imaging the target. And it is useful in checking various interference methods to ISAR imaging.
