Using space based sparse array for ground moving target indication is attractive. Unfortunately, range, Doppler and angle ambiguities usually occur with space based sparse array.

天基稀疏孔径实现地面运动目标指示（GMTI）具有很大吸引力，然而天基稀疏阵通常存在距离、多普勒和角度模糊。

Ground moving targets indication (GMTI) is an important application of spaceborne distributed radar. Distributed sparse array in space can improve the MTI performance with increased virtual aperture.

地面动目标检测(GMTI)是星载分布式雷达的重要应用之一，利用星载稀疏阵可增加系统虚拟孔径，以改善动目标检测性能。

The Parametric Adaptive Matched Filter (PAMF) is a good method for the Ground Moving Target Indication (GMTI) of bistatic airborne radars.

在双基机载雷达的地面动目标检测中，参数自适应匹配滤波器(PAMF)方法是一种很有效的方法。

But the massive ill-will that Blizzard has engendered to get this one project off the ground should be some indication of just what a misguided idea it was to begin with.

There's no indication that these particular officers were on the ground at the time in Haditha so it probably looks more to the reporting side of this.

At this time, we have no indication that the mishap was caused by anything or anyone on the ground.
