Downward-Looking 3D-SAR with Dual-Transmit and Multiple-Receive Linear Array Antennas Based on Time and Waveform Diversity

摘要：

The dual-transmit and multiple-receive (DTMR) configuration of linear array antennas (LAA) is firstly introduced in downward-looking 3D-SAR imaging in this paper. The geometrical model and the signal model based on the principle of time diversity and waveform diversity are analyzed. The three-dimensional imaging processing algorithm for downward-looking 3DSAR with DTMR-LAA is given via a stepwise mathematical derivation and the analytic expression of 3D PSF after 3D imaging processing is presented. The simulation results confirm the feasibility of the downward-looking 3D-SAR with DTMRLAA imaging concept.
