摘要：
A robust Capon adaptive beamfonning imaging method was proposed for stepped-frequency through-the-wall radar. According to the ideal of robust Capon beamforming(RCB) under the steering vector uncertainty set, Capon optimal weight vector in frequcency domain is obtained by accurately estimating Compensation function vector. Then signal energy is estimated by freqency weighting, and coherence factor(CF) weighting is applied to suppress sidelobe level. Therefore, this method not only achieves higher resolution and much better interference suppression capabilities, but also improves imaging contrast.
