Bandwidth Extrapolation Technique for Polarimetric Radar Data
Summary :
Range resolution for radar is determined by bandwidth. One of the various super-resolution techniques for improving resolution is bandwidth extrapolation (BWE). In this technique, a linear prediction model is fitted to the data, and the model is used to extrapolate the bandwidth. In this paper, we extend BWE, and propose a new algorithm that we call polarimetric bandwidth extrapolation (PBWE) applicable to polarimetric radar data. We show through numerical simulations that utilization of fully polarimetric information allows PBWE to improve the resolution beyond the conventional BWE method. Some results of a physical simulation experiment using a W-band polarimetric FMCW radar and corner reflectors are shown to confirm the advantage of PBWE.
