22467 首先，为了解决直接进行 3 维 Hough 变换计算量大的问题，将 3 维点迹依次降维映射至径向距离-时间、方位角-时间和仰角-时间 3 个平面进行 2 维 Hough 变换； Firstly, in order to reduce huge computational load problem from direct three-dimensional Hough transform, three- dimensional measurement points are mapped into range-time plane, azimuth-time plane and elevation-time plane in turn for two-dimensional Hough transforms.
22468 其次，为了能够在充分利用点迹能量信息的基础上尽量减小强干扰的影响，在每级 Hough 变换中采用非相参积累和二值积累相结合的双重积累方式进行点迹筛选； Besides, to decrease the impact from strong interference, meanwhile, make full use of energy information of points, point selection is carried on by double integration means of non-coherent integration and binary integration in every stage.
22469 最后，通过引入运动约束以及合并相似航迹的方式进行航迹精简，从而有效降低虚假航迹数，得到按照时序关联的最终检测航迹。 Finally, false trajectory will be reduced effectively by motion constraints as well as merging of similar trajectories and the final trajectory from sequence association can be obtained.
22470 仿真结果表明，该算法具有较高的航迹检测概率和较低的虚假航迹检测概率，可以实现对临近空间高超声速目标的有效检测跟踪。 Simulation results show that proposed algorithm can realize effective detection and tracking for near-space hypersonic targets with relatively high trajectory detection probability and low false trajectory detection probability.

In the case of the location method based on image matching target method will be invalid, when the target area does not have the matching point, such as: sea target, grassland target, etc.
22472 首先，在相邻合成孔径中心时刻，利用收发平台与目标的几何关系进行数学建模； First, a geometrical model between the transceiver platform and the target is constructed at the time of center of adjacent synthetic aperture.
22473 再结合地距 SAR 图像中的目标与场景中心点的关系，解算目标相对接收平台的位置信息； Then the position information of the target relative of the receiving platform can be solved by combining the relationship between the target in the SAR image and the center point of scene.
22474 最终，根据双基地前视 SAR 系统的特点，建立空时频同步误差模型，并结合仿真计算结果给出其对定位精度的影响规律。 Finally, according to the characteristic of bistatic forward-looking SAR system, the error models of synchronization errors are built. What is more, through the analysis of the simulation results, the influence of the error on the positioning accuracy is given.
