G01S 15/10

using transmission of interrupted, pulse-modulated waves (determination of distance by phase measurement G01S15/32)

Introduced: January 1980

Title

Titles differ between systems:

IPC: using transmission of interrupted, pulse-modulated waves

CPC: using transmission of interrupted, pulse-modulated waves (determination of distance by phase measurement G01S15/32)

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 interrupted, pulse-modulated waves

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 interrupted, pulse-modulated waves (determination of distance by phase measurement G01S15/32)

Of 5 combined children, 3 exist in both systems.

2 codes are CPC-only extensions.

IPC defines codes here since 1980.
