G01S 17/10

using transmission of interrupted, pulse-modulated waves (determination of distance by phase measurements G01S17/32)

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 measurements G01S17/32)

Full Title

Full titles differ between systems:

IPC:

Systems using the reflection or reradiation of electromagnetic waves other than radio waves, e.g. lidar systems > Systems using the reflection of electromagnetic waves other than radio waves > Systems determining position data of a target > for measuring distance only > using transmission of interrupted, pulse-modulated waves

CPC:

Systems using the reflection or reradiation of electromagnetic waves other than radio waves, e.g. lidar systems > Systems using the reflection of electromagnetic waves other than radio waves (G01S17/66 takes precedence) > Systems determining position data of a target > for measuring distance only (indirect measurement G01S17/46; active triangulation systems G01S17/48) > using transmission of interrupted, pulse-modulated waves (determination of distance by phase measurements G01S17/32)

IPC and CPC are identically structured here. All 3 subcodes exist in both systems.

IPC defines codes here since 2020.
