摘要：

A localization algorithm, which combines Hough transform and a modified high-order ambiguous function (MHAF) process, is proposed to precisely track multiple moving targets by dual-frequency continuous-wave through-wall radar (DF-CW TWR). To avoid the cross-term interference, a Hough-based separation method, which uses a novel progressive geometrical model, is first applied to decompose the echo. Then, an MHAF method is applied to real-time estimate the target instantaneous frequency. Finally, the target trajectories are synthesized based on the estimation results.
