界面反射超声散斑一阶统计特性

对界面反射超声斑场的一阶统计特性进行了理论和实验分析，在假设条件下，推导了超声散斑场的振幅分布和相位分布，实测数据显示理论与实验结果有很好的吻合，这表明理论假设是合理的并在实践中可行，这还表明，在B超影像分析中，超声扫描截面上散斑场统计特性的结果与该文的结果一致。

FIRST ORDER STATISTICAL PROPERTIES OF THE ULTRASONIC SPECKLES REFLECTED FROM AN INTERFACE

The first order statistical properties of the ultrasonic speckles reflected from an interface is analyzed theoretically and experimentally. Under the condition of some assumptions, the amplitude distribution and phase distribution of the ultrasonic speckles are conducted. The measurement shows that the theoretical conduction is in good agreement with the experimental results. It indicates that the theoretical assumptions are reasonable and practical. In the analyses of B Scan images, though the ultrasonic speckles are located in the ultrasound scan section, its analyzing results are identical with those in the present paper.
