PRRS Technical Review
PRRS does not approach sensing systems as an active interrogation problem. Instead, it views sensing as the extraction of structure from the ambient fields already present in the environment. Most sensing systems assume some level of cooperation, illumination, or signal dominance. In contrast, PRRS operates under the premise that the environment is already saturated. By focusing on anomaly detection through the observation of deviations rather than returns, the system reframes the concept of detection as the persistence of anomalies rather than mere target acquisition. This approach involves trading resolution for continuity. PRRS highlights a systemic asymmetry: systems designed to transmit information are often easier to observe than those intended to remain silent.
