G01S 15/32

using transmission of continuous waves, whether amplitude-, frequency-, or phase-modulated, or unmodulated

Introduced: January 1980

Full Title

Full titles differ between systems:

IPC:

Systems using the reflection or reradiation of acoustic waves, e.g. sonar systems > using reflection of acoustic waves > Systems determining position data of a target > Systems for measuring distance only > using transmission of continuous waves, whether amplitude-, frequency-, or phase-modulated, or unmodulated

CPC:

Systems using the reflection or reradiation of acoustic waves, e.g. sonar systems > using reflection of acoustic waves (G01S15/66 takes precedence) > Systems determining the position data of a target > Systems for measuring distance only (indirect measurement G01S15/46) > using transmission of continuous waves, whether amplitude-, frequency-, or phase-modulated, or unmodulated

Of 3 combined children, 2 exist in both systems.

1 codes are CPC-only extensions.

IPC defines codes here since 1980.
