Abstract :
The frequency-division linear frequency modulation MIMO (FDLFM-MIMO) radar is proposed in this paper, which can synthesize high-resolution range profile (HRRP) for ISAR/SAR imaging via a group of narrow-band LFM signals without over-demands on system bandwidth and sampling rate. Unfortunately, it is depicted that the HRRP sidelobes of the FDLFM-MIMO radar may be too high. According to the cause of the sidelobes, a novel alternative transmission scheme and an extended matched filter are proposed, and a weighting window is also applied. Finally, the numerical experiments are given to show the effectiveness of the methods.
