Which factor is NOT listed as influencing engagement geometry and intercept geometry?

• A. Target speed
• B. Altitude
• C. Radar coverage
• D. Weather conditions

Answer: (D)

Engagement geometry and intercept geometry come from how the target moves relative to the interceptor and how the sensors are arranged to observe and guide the intercept. The target’s speed determines how quickly the interceptor must close in and what lead angle is needed. The altitude sets the vertical separation and influences the range and timing of the intercept. Radar coverage defines what portions of space the system can see and track, shaping which intercept paths are actually possible. Weather conditions, while they can affect radar performance and sensor reliability, do not change these geometric relationships themselves; they influence effectiveness and detection but not the fundamental geometry used to plan or execute an intercept.
