摘要 用解析模型详细、深入的分析了更接近实际的非理想情况下新的幅度相消定位方案 (互换式幅度相消定位 )的性能 :分析了探测系统的分辨率和灵敏度有限及非完全交换时交换式幅度相消定位方案的定位性能 ;讨论了非完全交换时系统参量和异质子参量对其定位能力的影响。结果表明 :新方法可减小相对幅度和相位及异质子参量对系统的影响 ,明显地提高定位精度 ,探测到尺度和吸收系数更小、深度更深的异质子。 The localization performance of a new amplitude cancellation localization scheme (interchange amplitude cancellation localization scheme) under non ideal case according with actual condition is analyzed using analytical model, especialy the performance when the resolution and sensitivity of the detection system is limited, and the interchange between two sources is not complete. The effects of the parameters of the heterogenous object on the localization performance of the system using the new scheme are also discussed. The results show that the method can reduce the effects of the relative amplitude and phase between two sources on the system, obviously improve the localization precision, and detect the heterogeneity with smaller size, deeper and smaller absorption coefficient.
