Fig. 3From: Evaluation of a class of NLFM radar signalsSquared magnitude of fast Fourier transform which is proportional to PSD of the typical frequency function shown in Fig. 1. Edge frequencies have small PSD values and low frequencies have large PSD values. This agrees with SPP, as the edge frequencies have large derivatives and middle frequencies have large derivatives. In the end, we get a windowed PSD that should result in small AC sidelobesBack to article page
