BISTATIC FORWARD SCATTERING ISAR SIGNAL MODEL WITH DIGITAL AUDIO BROADCAST TRANSMITTER

Abstract

This work presents Bi-static Inverse Synthetic Aperture Radar (BISAR) signal model with a Digital Audio Broadcast (DAB) waveform. A BISAR topology with geometry that consists of stationary transmitter and receiver, and moving target is described. The object position in the space is determined by kinematic vector equations. Mathematical model of DAB signal reflected from a complex object is described. Two-dimensional (2-D) image reconstruction is implemented by applying correlation with an emitted waveform or Fourier transform on a range direction, and Fourier transform on an azimuth direction.
