Class Information
Number: 342/163
Name: Communications: directive radio wave systems and devices (e.g., radar, radio navigation) > Clutter elimination > Mti (moving target indicator) > With blind speed elimination
Description: Subject matter wherein circuitry is provided to compensate for targets having radial velocities such that the returned signals cancel each other to produce a false indication of a stationary target.
