针对双频连续波穿墙雷达（DF-CW TWR）对多运动目标的精确跟踪问题，提出了一种结合Hough变换和高阶模糊函数（MHAF）的定位算法。为了避免交叉项的干扰，Hough的分离方法，它使用了一种新的渐进的几何模型，首先应用到分解的回波。然后，应用MHAF方法实时估计目标瞬时频率。最后，根据估计结果合成目标轨迹。
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.
