Abstract

The bistatic configuration of linear array with one central antenna element for transmitting and the other antenna elements of linear array for receiving is introduced in downward-looking SAR for three-dimensional imaging in this paper. The geometrical model and the received signal model of downward-looking SAR using bistatic uniform linear array antennas are established. The analytic expression of three-dimensional imaging results is derived and the resolutions in three dimensions are given. This paper presents the image formation and analyzes the simulation results based on this 3D imaging concept.
