How can adverse weather affect SHORAD sensor performance and track timing?

• A. It has no effect on track timing.
• B. It can degrade radar and EO sensor range and resolution, impacting track quality and timing.
• C. It only affects maintenance schedules.
• D. It guarantees improved tracking under cloudy conditions.

Answer: (B)

Adverse weather affects SHORAD sensor performance by reducing both radar and EO/IR sensing range and resolution, which directly harms how accurately and quickly a target can be tracked. Rain, snow, fog, and clouds attenuate radar energy and clutter the return, lowering detection distance and degrading range and bearing measurements. At the same time, visibility for EO sensors drops, reducing contrast and detail so targets are harder to identify and track reliably. With fewer high-quality measurements each update and more noise in the data, the tracking system becomes less certain, update cadence can slow, and there’s a greater risk of track loss or delayed re-acquisition. Weather can also introduce more clutter and false alerts, making data association tougher and further impacting the timing of valid track updates.
