Area Array surveillance technique is defined as

Area Array surveillance technique is defined as

• A. Detectors set throughout a high value target for detection and early warning of a CBRN attack
• B. given geographic space
• C. uninterrupted checking
• D. frequent checks

Answer: (B)

Area array surveillance is all about covering a defined geographic space rather than focusing on a single point. The idea is to monitor activity across a region so you can detect movements or anomalies anywhere within that area, which is what the phrase “given geographic space” conveys. This spatial scope is what sets it apart from detector placement around a specific high-value target, which is about protecting one point rather than the entire area. It also isn’t about how often you check or how continuously you monitor; those refer to cadence or duration, not the geographic coverage.
