Real-Time Fourier Analysis of Spread Spectrum Signals Using Surface-Wave-Implemented Chirp-Z Transformation (Short Papers)

In many communication and RADAR applications it is desirable to determine the spectral content of signals in real time. A technique employing dispersive surface acoustic wave devices to implement the chirp-Z transform is described. The experimental results obtained for a number of commonly used signals, including the maximal-length pseudonoise sequences, are shown, and the agreement with theoretical prediction is discussed.
