Abstract :
A method for measuring the nonlinear frequency modulation of a LFM (linear frequency modulated) signal generated by a SAW device with large bandwidth and long pulse duration is described. The measured results are processed by computer and their effects on the ISAR (inverse synthetic aperture radar) imaging are discussed
