Abstract UWB SAR works usually in low Signal-to-Clutter Ratio (SCR) conditions in order to detect targets hidden in forest or buried in ground. A Time-Frequency Representation Image Formation (TFRIF) is proposed in this paper, which can get a series of SAR images of different spatial frequency without loss of resolution. The SCR is improved through fusion of those images. The efficiency of TFRIF is proved with real data.
