| Abstract: The various technologies presented herein relate to incorporating one or
more notches into a radar spectrum, whereby the notches relate to one or
more frequencies for which no radar transmission is to occur. An
instantaneous frequency is monitored and if the frequency is determined
to be of a restricted frequency, then a radar signal can be modified.
Modification can include replacing the signal with a signal having a
different instantaneous amplitude, a different instantaneous phase, etc.
The modification can occur in a WFS prior to a DAC, as well as prior to a
sin ROM component and/or a cos ROM component. Further, the notch can be
dithered to enable formation of a deep notch. The notch can also undergo
signal transitioning to enable formation of a deep notch. The restricted
frequencies can be stored in a LUT against which an instantaneous
frequency can be compared. |
