Interference Avoidance

Technique
Method
Implementable in
TI device.
Usefulness and
simplicity
1
CFAR
–
based
mitigation
Increase the CFAR thresholds
accounting for the interference.
This decreases the detection
sensitivity but avoids spurious
sidelobes.
Yes. The detection
threshold is user
programmable.
Debatable usefulness.
Very simple to
implement.
2
Dithering in
time domain.
Dithering the idle time (time
between chirps) or the interframe
time (time between frames). Since
this dither is different for the
Yes. A near infinite
variation is possible on
the ‘idle time’. Frames
can be generated with
Very Useful. specially in
a parallel interferer
scenario. Simple to
implement
