摘要
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 bistatic and multistatic radar system possesses many more advantages on the perfor- mance of anti--jamming, anti--ARM, anti--lwo--level--intrusion and anti--stealthe than monostatic radar. Its main tactical technological parameters, such as detection coverage and lo- eating precision which are influenced by many complex factors, are different from those of the conventional radar. In this paper, on the basis of an analysis of detection coverage, the compu- tation formula of detection coverage is drived. On the analysis of locating precision, the target entering detectable region of the system from different directions is considered, the curves of locating precision are drafted and the methods of improving locating precision are proposed. It is worth noticing that the locating precision of the system is disappointing when the target is near the baseline, but that at this moment, the discoverage probability of system is good be- cause the radar system presents bigger β(bistatic radar angle). So, there is contradiction be- tween discovering target and measuring precision to stealth objective. This is an outstanding, important problem in bistatic and multistatic radar.
