Abstract :
The authors compare two of Thomson´s multiwindowed spectral estimation methods to conventional windowed discrete Fourier transform (DFT) methods for generating inverse synthetic-aperture radar (ISAR) images. The compared images are generated from synthetic data and data obtained from the IPIX research radar. The images show that Thomson´s adaptive multiwindowed spectral estimation method is superior to the windowed fast Fourier transform (FFT) in generating ISAR images
