双(多)基地雷达体制在“四抗”性能上具有单基地雷达无法比拟的优点,其定位精度与探测范围等主要战术技术参数与常规雷达有很大不同,影响它的因素是相当复杂的。在探测范围分析中,文中推导出了它的计算公式;在定位精度分析中,考虑了目标从不同方向进入系统探测区时,其定位精度曲线,并提出改善定位精度的方法,值得注意的是:当目标进入基线附近时,其定位精度变差,此时正是雷达系统呈现较大的双基角β,发现目标的概率变大。因此,对隐身目标就有发现目标与测量精度的矛盾存在,这是双(多)基地雷达的一个突出的、值得重视的问题。
The dual (multi) base radar system has the unmatched advantages of single base radar in the “fourth resistance” performance. The main tactical and technical parameters such as positioning accuracy and detection range are quite different from those of conventional radar. The factors influencing it are rather complicated . In the analysis of the detection range, the paper deduces its calculation formula. In the analysis of the positioning accuracy, when the target enters the system detection zone from different directions, the positioning accuracy curve is proposed and the method to improve the positioning accuracy is proposed : When the target enters near the baseline, its positioning accuracy becomes worse. At this time, it is the radar system that has a larger birefringence β, and the probability of finding the target becomes larger. Therefore, there is a contradiction between the discovery target and the measurement accuracy for the stealth target, which is a prominent and worthy issue of the dual (or multi-base) radar.
