using transmission of interrupted, pulse modulated waves (determination of distance by phase measurement G01S13/32)

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 G01S13/32)

Full Title

Full titles differ between systems:

IPC:

Systems using the reflection or reradiation of radio waves, e.g. radar systems; Analogous systems using reflection or reradiation of waves whose nature or wavelength is irrelevant or unspecified > Systems using reflection of radio waves, e.g. primary radar systems; Analogous systems > 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 radio waves, e.g. radar systems; Analogous systems using reflection or reradiation of waves whose nature or wavelength is irrelevant or unspecified > Systems using reflection of radio waves, e.g. primary radar systems; Analogous systems > Systems determining position data of a target > Systems for measuring distance only (indirect measurement G01S13/46) > using transmission of interrupted, pulse modulated waves (determination of distance by phase measurement G01S13/32)

Of 10 combined children, 8 exist in both systems.

2 codes are CPC-only extensions.

1 shared codes have differing titles between IPC and CPC.

IPC defines codes here since 1980.
