Geniş bant - geniş açı ters yapay açıklıklı radar (TYAR) görüntüleme algoritması geliştirilmesi ve nümerik uygulamaları

, 2020
Inverse Synthetic Aperture Radar (ISAR) is a powerful signal processing technique for imaging moving targets in range and cross-range domains. In this thesis, scattering EM field is collected within a wide band ? wide angle range. If this is the case, FFT method cannot be readily used for 2D ISAR imaging application.
