Hybrid Radar Fusion with Quantization: CRB-Rate Trade-offs and ADC Dynamic Range

This paper extends the hybrid monostatic-bistatic radar fusion framework to explicitly account for analog-to-digital converter (ADC) quantization. The resulting analysis exposes the trade-off between sensing accuracy (via the Cramer-Rao bound) and achievable communication rate under finite ADC dynamic range, providing design guidance for practical hardware-constrained ISAC receivers.
