G01S 13/92

for velocity measurement

Introduced: January 1980

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 > Radar or analogous systems, specially adapted for specific applications > for traffic control > for velocity measurement

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 > Radar or analogous systems specially adapted for specific applications (electromagnetic prospecting or detecting of objects, e.g. near-field detection, G01V3/00) > for traffic control (G01S13/93 takes precedence) > for velocity measurement

No child classifications to compare. This is a leaf node in both IPC and CPC.
