INVESTIGATION OF TRANSFORM TECHNIQUES FOR DIGITAL PROCESSING OF RADAR SIGNALS VolumeⅠ

摘要

The purpose of this report is twofold. Efficient and general fast Fourier transform (FFT) programs are developed to handle arbitrary factors. The unscrambling is always performed in one step. However, the main goal of the report is to investigate the application of transforms other than the FFT to radar signal processing. Since Hadamard transform processing is sensitive to delay, a bank of filters must be used so that the advantage of fast computation is lost except possibly for special signals. The same problem is encountered with other generalized transforms. Finally, the R-transform and the Mersenne transform are considered. The Mersenne transform can perform discrete convolutions efficiently, but it requires computer words of large size.
