基于三维序列探地雷达目标自动定位方法研究

Automatical locating targets method based on three-dimensional series in ground penetrating radar

针对三维探地雷达目标定位问题,基于序列目标特征位置提出了一种自动定位埋地目标的方法。该方法采用并行变长自适应滤波器组自动消除直达波,用最佳检测小波在不同的尺度上统计检测和定位目标,并根据点目标的成像特征确认可疑目标,最后采用电波在媒质中速度的估计值实现目标三维聚焦。通过实测数据验证了该方法的正确性和可行性。

On the basis of extracting three-dimensional （3-D） features of the buried target automatically, a novel location method for the ground penetrating radar in presented in this paper. Theoretically, it eliminates the direct wave by parallel-adaptive filter banks, then an optimal detecting wavelet is used to determine the possible target statistically, finally the 3-D buried target is affirmed based on the signature of a point target and focused by the estimation of the velocity at which the wave transmits the medium. The experiments demonstrate that this method is of well available and effective.
