摘要

希尔伯特变换处理器通过感知总能量到达的速率来改进零件的缺陷检测。该处理器采用单边带转换技术进行实时操作。建立了传感器带宽为0.5 ~ 20mhz的上边带处理器，可分辨间隔为90ns的回波。下边带处理器的带宽为2至42兆赫，可以分辨间隔60秒的回波

Real-time analytic signal processor for ultrasonic nondestructive testing

Hilbert transform processors have been developed to improve flaw detection in parts by sensing the rate of total energy arrival. The processor operates in real time by using a single-sideband conversion technique. An upper sideband processor has been built with a transducer bandwidth of 0.5 to 20 MHz and can resolve echoes 90 ns apart. A lower sideband processor has a bandwidth of 2 to 42 MHz and can resolve echoes 60 ns apart.<>
