Sense-of-movement determination

Systems using the reflection or reradiation of acoustic waves, e.g. sonar systems > using reflection of acoustic waves > Systems of measurement based on relative movement of target > Velocity or trajectory determination systems; Sense-of-movement determination systems > Sense-of-movement determination
