6. RADAR
6-25
* Radial component of target velocity: The target velocity can be separated into two
components, the radial and transverse components, as in the figure below. The radar
is only able to sense the motion directly along the radial, either towards or away from
the radar, because the transverse component has no effect on the phase of the return-
ing electromagnetic wave.
