RADAR/LIDAR: MCOLES Speed
Measurement Course
People vs Ferency: The 7 Guidelines - ANS Courts ruled that in order to avoid any violation of
due process rights of a defendant in a speeding case involving "moving" radar, seven guidelines
must be met:
1. Officer operating radar has adequate training and experience in its operation.
2. Radar device was in proper working condition and properly installed at the time of the
issuance of the citation.
3. Radar device was used in an area where road conditions had minimum possibility of
distortion.
4. Input speed of the patrol vehicle was verified. In other words, speedometer is calibrated and
updated.
5. Speedometer retested at the beginning and end of shift.
6. Officer can testify the vehicle was within the operational area of the beam at the time the
reading was displayed.
7. Officer has been certified for use by a qualified agency.
RADAR Stands For.... - ANS RAdio Detection And Ranging
TEST QUESTION: Functions of the Radar - ANS 1. Uses Doppler Shift Principle
2. Radio Signal of Frequency Bounces of Target (the Doppler Effect or Doppler Shift Principle)
3. Changes in Frequency are Measured
***NOTE***
Know what the Doppler effect is for the test.
More cycles per second indicate a receding target, and fewer cycles per second indicate an
approaching target. True or False? - ANS False.
More cycles per second indicate an approaching target. Fewer cycles per second indicate a
receding target.
, ***NOTE***
More = Approaching Target
Fewer = Receding Target
Redshift - ANS A Doppler Shift in which spectral features are shifted to longer wavelengths
when an object is moving away from the observer.
_______________ is the distance between ______ corresponding parts of a wave.
A) Wavelength, 2
B) Inertia Measurement, 3
C) Radar Distance, 4 - ANS A) 2
Radar Sensitivity __________ against Metal, Stone, Wood, and Concrete?
A) Reflects
B) Refracts
C) Absorbs - ANS A) Reflects
Radar Sensitivity __________ against Grass, Leaves, Trees, or Sand (the Earth)?
A) Reflects
B) Refracts
C) Absorbs - ANS C) Absorbs
Radar Sensitivity __________ against Glass or Plastic?
A) Reflects
B) Refracts
C) Absorbs - ANS B) Refracts
Radar detectors are legal in Michigan, except when using a Commercial Motor Vehicle. True or
False? - ANS True. Civilians are legally allowed to have radar detectors. If you are operating a
Commercial Motor Vehicle however, this is illegal.
Main Lobe radiates in the __________ direction as an antenna?
A) Opposite
B) Same - ANS B) Same
The Operational Area of the radar device is the ______ aimed antenna in the __________
mode.
