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 > wherein range gates are used

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) > wherein range gates are used

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