Accurately calculate the speed measurement error introduced by a transmit frequency offset in vehicle radar systems. Ideal for engineers, technicians, and students analyzing automotive radar performance, speed gun calibration, and sensor precision. Understand how frequency stability impacts reported vehicle speeds instantly.
Formula:
The calculator determines the calculated speed and the resulting error based on the actual target speed, nominal transmit frequency, and the actual transmit frequency.
- Calculated Speed (vcalculated) = vactual * (fT_actual / fT_nominal)
- Speed Error (verror) = vcalculated - vactual
- Percentage Speed Error (%) = (verror / vactual) * 100
Where:
- vactual = Target's Actual Speed
- fT_nominal = Nominal Transmit Frequency (expected)
- fT_actual = Actual Transmit Frequency (with offset)
