6289 用不同系统采集的PolSAR数据进行的实验结果表明,与精致LEE滤波、NL-Pretest滤波以及最新的滤波方法相比,本文算法不仅能够有效抑制相干斑噪声,而且图像的边缘和极化散射特性也得到了更好地保持。 With different PolSAR data from the system of the experimental results show that with delicate LEE filter, NL - compared to Pretest filter and the latest filter method, this algorithm not only can effectively restrain, coherent noise and the edge of the image and also had better maintain the polarization scattering characteristics.
6290 针对空中交通管制中的冲突探测与解脱问题,提出了一种几何最优的冲突探测与解脱方法。 For air traffic control problem of conflict detection and release a geometric optimal methods of conflict detection and relief.
6291 首先定义了该问题的冲突解脱点,在该点处预判飞机之间可能存在的飞行冲突。 First defines the problem of conflict points, at this point to predict possible flight conflict between aircraft.
6292 其次,采取同向同角度的方式解决飞行冲突,即在原航迹上两机同时向同一侧改变相同角度,得到新的航迹交叉点,即航迹恢复点,使得两机之间始终保持最小安全距离。 Second, take the same way to solve flight conflicts with the Angle, the two machine on the original track and the change on the same side as the same Angle at the same time, get the new track intersection, the track recovery point, makes always keep the minimum safety distance between two machines.
6293 通过几何分析,理论推导了两机航迹距离之和与各自改变航向角度之间的关系,该模型能够有效地解决飞行和冲突,并且具体给出冲突解脱和航迹恢复的位置,以及所涉及到的参数求解过程。 Through geometric analysis, theoretical derivation the sum of the two machine track distance and their change direction Angle of the relationship between the model can effectively solve the flying and conflict, and conflict are specified by the relief and the position of the track is restored, and the parameters involved in the solving process.
