摘要
根据Ｔ／Ｒ－Ｒ型双基地系统在受到由弱到强的干扰影响时，其可用的测量量不同，有必要研究各种干扰模式下应采用的跟踪算法，提出了分段跟踪技术，充分利用了不同干扰强度时Ｔ／Ｒ站和Ｒ站的测量数据，提高了对三维运动目标的跟踪精度。通过典型目标航迹的计算机仿真，对算法性能做了评估。
hen the T R-R bistatic system is under the influence of an increasing interferenee.the usable measurements in it are variable,Therefore it is neeessary to study track-ing algorithms coneeming different interference modes.A dividual tracking technique is pro-posed,which makes full use of measuring data in T/R and R station under different interference intensities;as a result,the tracking precision of 3-D moving target is increased.The per-formance of these algorithms is evaluated with the help of computer simulation for typical target paths.
