NOT a saturation alleviation method?

• A. DLR
• B. DSR
• C. Alternate Search Sector 1
• D. Alternate Search Sector 3

Answer: (D)

When a radar system is overloaded by more targets than it can handle at once, the goal is to reduce the load on the busiest parts of the system so critical updates stay timely. Methods that achieve this include lowering processing demands (dynamic load reduction), moving some tracking or search responsibilities to other sectors (dynamic sector reassignment), or shifting the search effort to an alternate sector to balance the workload.

Dynamic load reduction and dynamic sector reassignment are directly about letting the system breathe under heavy traffic. Shifting search to an alternate sector also helps by spreading the demand. The option described as Alternate Search Sector 3, however, does not fit as a saturation relief method in this context because the standard approaches used to relieve saturation involve altering load or reallocating tasks among sectors in a way that reduces peak burden; sector 3 in this scenario isn’t used for that relief, so it wouldn’t alleviate saturation.
