摘要： 本文针对阵列式天线探地雷达系统的目标成像问题，理论模拟分析了最小二乘（LS）估计、Capon估计、幅度相位估计（APES）三种波束形成算法在目标回波到达角（direction of arrival，DOA）估计上的效果和精度，提出了基于DOA估计的阵列式探地雷达逆向投影目标成像方法。该方法综合利用多输入多输出（MIMO）阵列信号估计得到的目标回波信号DOA和阵列空间观测信息对目标体进行成像，通过成像点空间扫描对各测点估计DOA幅度值在成像点的加权积分进行目标定位及反射强度估计。该方法实现简单高效，可以广泛应用于地下简单目标体的快速成像。

Abstract: Taking the target imaging of array type ground penetrating radar system as the topic, the authors analyzed the effect and accuracy of the estimation for target echo arrival upon direction of arrival (DOA) in theoretical modeling with three beam forming algorithms, i.e., least square (LS), Capon algorithm and amplitude phase estimation (APES), and put forward a method of array type GPR target imaging based on DOA estimation. This method images the target by integrating the target echo arrival signal estimated from multiple-input-multiple-output(MIMO)array signals with the spatial information obtained from multiple array observations, and localizes target and estimates reflection intensity by the imaging points weighted integral based on the DOA amplitude value estimated from each point by way of imaging points spatial scanning. This method is simple and efficient, and can be used widely in the rapid imaging of simple underground targets.

Key words: least squares (LS), Capon algorithm, amplitude and phase estimation (APES), DOA estimation, target imaging, ground penetrating radar(GPR)
