High-resolution SAR/ISAR imaging with chaotic noise signals

We present the airborne SAR imaging results and the ground-based ISAR imaging results with our developed Ku-band and Ka-band radar systems. In these experiments, chaotic noise waveforms are used as the transmitted signals combined with the stepped-frequency technique so as to achieve larger bandwidths. For SAR imaging, two-channel interferometric results are demonstrated while for ISAR imaging, dual-polarization results are demonstrated.
