G01S15/325 - CPC Classification

Classification description:

Systems using the reflection or reradiation of acoustic waves, e.g. sonar systems using reflection of acoustic waves; Systems determining the position data of a target; Systems for measuring distance only using transmission of continuous waves, whether amplitude-, frequency-, or phase-modulated, or unmodulated using transmission of coded signals, e.g. of phase-shift keyed [PSK] signals
