本文研究了边搜索边跟踪(TWS)雷达对具有一定角宽度的斯维林1和斯维林2型目标的精度。该项研究使得对在波束扫描期间目标处场强变化的影响有了深入的认识。通过和单脉冲技术的知识相结合的方法,文中提出了改进边搜索边跟踪雷达精度和分辨力性能的方法,并从理论上对这些方法进行了设计和评价,对真实目标作了实际测量。结果指出,对于快速衰落和闪烁的以及处于人为干扰环境中的目标在精度上有明显的改善。对于接近的空间目标,目标间相距为0.5～0.7波束宽度的间隔时,对多目标状态探测及角位置精确估值两方面,结果也表明性能十分良好。
In this paper, we study the accuracy of edge search edge-tracking (TWS) radar for Svein 1 and Svein 2 targets with a certain angular width. This research has led to a deep understanding of the effect of field strength changes at the target during beam scanning. By combining with the knowledge of single pulse technology, the paper presents a method to improve the accuracy and resolution performance of edge-searching edge-tracking radar. The methods are designed and evaluated theoretically, and the actual target is measured. The results indicate that there is a significant improvement in accuracy for targets that are rapidly fading and flicker and in a man-made environment. For close space targets, the target spacing between the 0.5 ~ 0.7 beam width interval, the multi-target state detection and angular position of the two estimates, the results also show that the performance is very good.
