Which statement best describes the purpose of MTI/CFAR in radar tracking?

Explanation:
MTI and CFAR are processing tricks that make real targets stand out against clutter and noise. MTI (Moving Target Indicator) suppresses stationary returns—ground, buildings, and other non-moving scenery—by using Doppler differences, so moving targets keep a detectable signal while clutter is reduced. CFAR (Constant False Alarm Rate) adapts the detection threshold to the local noise and clutter level, keeping the chance of a false alarm steady even when conditions change. Put together, they help separate real targets from interference by both reducing the impact of clutter and ensuring targets rise above the adaptive threshold. They aren’t about degrading sensitivity or randomizing detection.
