Empty distance data fluctuation analysis

Scenario 1: Decreasing empty distance

• Fluctuation ≤ 0.4 m: Likely antenna echo interference.

• Fluctuation > 0.4 m: Obstacles exist between radar and target.

Scenario 2: Increasing empty distance

Readings are approximately twice the actual value: Secondary echo interference is the primary cause.
