Section 8--Interference
8.4
7. Heater and A/C fan motors can cause conventional
analog radar units to display the fan's speed, rather than
a weaker target vehicle's speed. The Eagle II's DSP
processing attempts to distinguish fan speeds from
actual vehicles and will ignore fan interference signals.
Refer to Sec. 7.5, "Setting Fan Interference Filter
Mode".
NOTE: Refer to the National Highway Traffic Safety
Administration's Basic Training Program in
RADAR Speed Measurement, June 1991, for
further information on interferences and training
guides.
