Abstract

During the design and development of multi-functional airborne hazard detection and avoidance radars, as well as radar navigation functions, we usually need a precise and reliable simulation evaluation. However, the existing solutions are usually highly proprietary for specific developers. In previous studies, we developed PASIM as one possible framework to unify the multi-functional radar developments. In this study, more novel enhancements and applications of PASIM are introduced based on the needs of communities, and the software tools are updated specifically for airborne radars. These updates include: (1) Enhancement and evaluation of airborne radar ground clutter modules, which supports different terrain or water surface types. (2) Combination of measured data as part of simulations. In this case, we used NASA’s pulsed-Doppler weather radar data as “meta-truth” and created simulation examples of a new generation of Sense and Avoid (SAA) simulation operation based on them. (3) Incorporation of realistic target impulse responses, RF channel modeling and processing chain. (4) Incorporation of automatic radar mode optimization, ground clutter mitigation solution and algorithms. (5) Enhanced data quality evaluation for both air-target tracking and weather surveillance. A generic airborne pulsed-Doppler radar with reasonable system parameters are used for our studies as an example and the design/evaluation procedure and results are presented.
