Ultrasonic Imaging Detective System Based On Spread Spectrum Technology

摘要：

In this paper introduce spared spectrum technology into ultrasonic imaging. Analyze how to modulate ultrasonic with the spread spectrum technology, introduce imagining restoration method, and then use this technology to detective the structure of five mine wells. Firstly, use pseudorandom codes to modulate ultrasonic signal before it is sent out, and then demodulate echo to obtain the Time difference. Secondly, apply gradual linear iterative method and QR decomposition of least squares method to restore image. Analyze the image with computer we can obtain the structure of objects. Experiment verified introduce spared spectrum technology into ultrasonic imaging can improve the resolution and accuracy.
