HI Jean,
This is territorial behavior: the cardinal is reacting to her reflection in the
window as if it is an intruder that won't back down or leave. You can avoid it
by hanging or putting something on the OUTSIDE of the window to break up or
hide the reflection. Pulling down a blind inside does not work: the bird will
still see her reflection on the outside.
You could cover the outside of the window completely with some fabric, but if
you want to be able to see out cover it with garden netting or some other
transparent material. You could stick vertical strips of tape across the
window, or put transparent decals on it, tack long strips of paper from the
frame if it's wood. These strategies also help avoid bird collisions with
windows.
For many other ideas see the Lab of Ornithology page about keeping birds safe
from windows:

Subject: [cayugabirds-l] Female cardinal attacking window
A female cardinal has been continually attacking my bedroom window for several
weeks. I've tried keeping a light on, and pulling the shades down to no avail.
There is a large forsythia bush beneath the window which has been a male
cardinal perch for years and an adjacent bridal wreath shrub has been a common
nest site for a pair. What is this behavior and should I do anything about it.
If so, what are some suggestions?
