Simulation and Adaptive Sub-Array Packing for an All-Digital Phased-Array Radar

Abstract

Increased flexibility afforded by all-digital radar architectures and operational concepts such as MIMO radar can be leveraged with new waveforms and aperture allocation methods to improve radar performance in diverse situations. A phased-array/MIMO continuum of operation is possible through all-digital architectures and further increases the degrees of freedom for adaptive-transmit radar. This paper describes modeling of this flexibility provided by all-digital radar and initiates potential strategies for waveform designs and aperture segmentation for improved performance in dense environments.
