  Leading autonomous vehicle (AV) platforms and testing infrastructures are,
unfortunately, proprietary and closed-source. Thus, it is difficult to evaluate
how well safety-critical AVs perform and how safe they truly are. Similarly,
few platforms exist for much-needed multi-agent analysis. To provide a starting
point for analysis of sensor fusion and collaborative & distributed sensing, we
design an accessible, modular sensing platform with AVstack. We build
collaborative and distributed camera-radar fusion algorithms and demonstrate an
evaluation ecosystem of AV datasets, physics-based simulators, and hardware in
the physical world. This three-part ecosystem enables testing next-generation
configurations that are prohibitively challenging in existing development
platforms.
