using frequency agility of carrier wave

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 > 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 > using frequency agility of carrier wave

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) > using frequency agility of carrier wave

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