The Vector Network Analyzers have mighty test function,its test precision and stability depend upon raw performance of the microwave hardware,the performance of calibration standards and the quality of the error correction technique.
矢量网络分析仪具有强大的测试功能 ,其测量精度和测量稳定性主要取决于校准标准件的性能、采用的误差修正技术和微波件的初始指标所决定 ,本文分别讨论了这三方面对矢量网络仪测量的影
The Vector Network Analyzers have mighty test function,it’s test precision and stability dependent upon raw performance of the microwave hardware、the performance of calibration standards and the quality of the error-correction technique,In this paper,these two facets about the vector network analyzer’s test are discussed.
矢量网络分析仪具有强大的测试功能,其测量精度主要取决于校准标准件的性能、误差修正技术所决定,本文分别讨论了这两方面对矢量网络仪测量的影响。
In this paper , we used the structral invariance of local minutiae to found local vectors, then integrate the best matching point and its neighbour points to get more accurate parameters of alignment adjustment, at last, we integrate multi-discriminant to complete fingerprint matching .
其优点是:将匹配分为两步进行,减少了拒判时间;初匹配利用了细节点间的局部结构关系,既克服了图像的平移和旋转也得到了更精确的坐标校准参数;二次匹配阶段,整合多种判决条件作为识别的依据,提高了识别率。
