Discrimination is defined as which of the following?

• A. The process of distinguishing real objects of interest from other objects or phenomena.
• B. The process of identifying friend or foe.
• C. The process of computing target range.
• D. The process of tracking the positions of a moving object.

Answer: (A)

Discrimination is the process of separating real targets of interest from clutter and non-threats in the sensor data. It lets you ignore unwanted reflections—like birds, weather returns, debris, or decoys—and focus on objects that could require engagement. Identifying friend or foe is a related task, but it’s a separate identification step; discrimination is about distinguishing targets from non-targets first. Computing target range and tracking the positions of a moving object are different functions—range calculation and motion tracking—whereas discrimination is about filtering the data to decide what could be a real target worth further action.
