Micro-Doppler Effect Analysis Based on Inverse Synthetic Aperture Imaging LADAR

摘要：

Although the micro-Doppler (m-D) effect can provide additional information for target recognition, the microwave radar cannot afford enough resolution to detect the m-D effect of small targets and long distance targets. To obtain high range resolution for the extraction of the fine m-D signatures, inverse synthetic aperture imaging LADAR (ISAIL) is used here. Because of the frequency modulation continuous wave (FMCW) laser signal is used in ISAIL, the m-D effect of ISAIL is different from the microwave radar. In this paper, the m-D effect of ISAIL is analyzed and compared with that in Xband radar. The experiment results show that ISAIL can offer sufficient information of micro-motions when the feature of motions is tiny.
