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 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.

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。

This method has the advantages of having a high locating precision and ignoring the change in pose of the moving object. The principles are introduced, the computer simulation and the experimental demonstration are given, the practicality of this method is discussed.

缺陷在构件内部所处的位置是产品质量评估的一个重要依据。在基于双目视差法进行缺陷深度定位的技术中,匹配对应点的选取非常关键。一般采用缺陷边缘或缺陷形状中心作为匹配点进行视差计算,实验表明此类方法具有很大误差。因此,文中提出一种基于能量中心匹配的缺陷深度定位技术,并通过设置人工缺陷进行精度分析,结果表明该算法能达到很高的定位精度。
