Imaging laser radar (ladar) systems have been developed for automatic target identification in surveillance systems. Ladar uses the range value at the target pixels to estimate the target's 3-D shape and identify the target. For targets in clutter and partially hidden targets, there are ambiguities in determining which pixels are on target that lead to uncertainties in determining the target's 3-D shape. An improvement is to use the polarization components of the reflected light. We describe the operation and preliminary evaluation of a polarization diverse imaging ladar system. Using a combination of intensity, range, and degree of polarization, we are better able to identify and distinguish the target from other objects of the same class.
成像激光雷达（Ladar）系统已被开发用于监视系统中的自动目标识别。激光雷达利用目标像素处的距离值来估计目标的三维形状并识别目标。对于处于杂波中的目标和部分隐藏的目标，在确定哪些像素位于目标上时存在模糊性，这会导致在确定目标的三维形状时产生不确定性。一种改进方法是使用反射光的偏振分量。我们描述了一种偏振分集成像激光雷达系统的操作和初步评估。通过结合强度、距离和偏振度，我们能够更好地识别目标并将其与同一类别的其他物体区分开来。
