In this paper, the concept of using Waveform Diversity (WD) with the Doppler Beam Sharpening (DBS) technique for airborne radar systems is investigated with a set of preliminary simulations. WD provides the ability to produce simultaneous multiple beams pointing in various directions without reliance on phase shifters. By using the DBS technique which exploits the Doppler shift of targets within each beam, multiple targets can be resolved and detected within the same range-azimuth cell. The combination of WD and DBS is unique and can provide airborne radar with faster and enhanced coverage, resolution and imaging. This study shows how two orthogonal linear chirps can be used to transmit two simultaneous beams pointing in two different directions with a linear antenna array. It also demonstrates how targets in the same range-azimuth cells can be resolved inside each beam with the combined use of DBS. Insights on critical requirements and directions for future work are also discussed.
