Additionally, as audio equipment require low-frequency noise measures, the Prohibit Audio Frequency (PAF)(3) function can set the minimum frequency to 30 kHz. 3. (JCN Network, Japan)
NIST helping improve speed measurements for cars, bullets May 22, 2009
The calibration methods studied included a radar target simulator (an audio frequency source best used in a test facility and designed to mimic various speeds of a moving object), tuning forks (provide a range of audio frequencies that simulate different vehicle speeds and are easily used in the field), a calibrated speedometer (where the DTR measurement is dependent on accuracy of the test car's speedometer) and a fifth wheel (using the measured speed of a wheel attached to the rear of the test...
