Abstract:
It is well known that the resolution of conventional radar is typically limited by the bandwidth of adopted waveform. However, we should not forget that the potential spatial resolution that radar can achieve could be much better, more precisely, in the order of sub-wavelength. Such radar operating °mode is called radar tomography, which exploits the spatial diversity, instead of large waveform bandwidth, to achieve super high spatial resolution. Although the theory of radar tomography had been developed for decades, very few experimental validations were reported in public literatures. In this paper, the investigations on radar tomographic imaging are conducted and validated with the measurements in microwave anechoic chamber. The spatial resolutions achieved in the experiments show good agreement with theoretical results.
