摘　　要：声表面波(SAW)线性调频变换(CZT)信号处理技术实用化研究是超声电子学重要课题之一。本文将就实用SAW CZT功率谱仪研制中涉及的诸如频率分辨率、测频精度及结构选择等设计细节,及其噪声、温度稳定性等性能分析问题作深入讨论。Though there have been a large number of studies on surface acoustic wave chirp z transform processors in their operating principle, it still is a necessary step to demonstrate their practicability in the use of real time signal processing. In this paper a couple of practical problems in design and analysis of SAW CZT spectrometer, such as the definition of frequency resolution, the choise of available data postprocessing technique and the analyses of it's noise behaviour and temrpeture stability etc., will be gone through.
