The detection performance of FFT processors for narrowband signals / R. S. Walker ; approved by R. F. Brown. : D68-21/5-1982E-PDF

"The report analyses the detection performance of the Fast Fourier Transform (FFT) type signal processor for narrowband signals in white Gaussian noise. Sinusoidal and narrowband Gaussian signals are considered. The signal processor structure is based on the short-time averaged periodogram approach to spectral estimation. Processor parameters considered in the study include time-bandwidth product, data windowing, periodogram overlap, FFT zeroes extension and data normalization. A building-block approach is adopted, whereby the effects of each parameter on the detection threshold can be determined. Results are presented in graphical form. Hence, for a selected set of processor parameters, the appropriate detection threshold can be readily obtained. A thorough mathematical treatment of the problem is presented in the Appendices"--Abstract, page ii.
