✦ Synopsis

This paper presents a new two-dimensional SAR imaging technique using DFT processing of linear arrays with transverse motion operating in the sequential mode (DFTSQM).

High-resolution images are generated without the need of range gating. Multiple target detection is performed on the basis of angular (azimuth and elevation) coordinates. No phase shifting or tapering hardware is required. Computer simulation and an example show the impulse invariance, and indicate that the new system's performance is comparable to standard SA R processing.
