  • Abstract
    Traditional beam formation and waveform techniques rely on fixed apertures with single frequency assumptions that restrict the geometry of the aperture. This approach results constraints on the functionality of radar systems such as having simultaneous imaging and tracking ability, eliminating complex interference, and working with platforms that have limited bandwidth and processing resources. We propose an adaptive multiresolution orthogonalized sub-space beam formation method (AMOS) that allows optimization of apertures that may have non-uniform spacing with limited bandwidth. We combine this model with a partially coherent electromagnetic wavefront propagation model. We will show how this method compares to similar methods from a theoretical lower bound standpoint.
