Abstract : MITRE has enhanced the capabilities of the Advanced Airborne Radar Simulation, a flexible end-to-end steady-state simulation that can be used to evaluate the critical issues affecting the performance of advanced airborne radars that use adaptive antenna techniques, i.e., space-time processing (STP), for both jamming and clutter suppression. For a large phased-array antenna, the limitations of a practical implementation of optimal STP will generally require suboptimal adaptive array architectures, such as element space, beam space, and subarrays. The simulation was modified to augment these suboptimal architectures with spatial degrees of freedom in elevation. The received signal models, i.e., target, jamming, and clutter, were modified to include the effects of near-field scattering using a multiple point scatterer model.
