Measurement Noise

Measurement Noise

Observational Noise

An error resulting from an inaccurate measurement. Many analysts use multiple indicators and multiple measurements of the same indicator to reduce observational noise as much as possible. It is also called measurement noise.

In general, measurement noise is mingled in the feedback signal coming from the sensors, which means that the noise signal exists for real.
The novel solution that this patent protects results in a very small and efficient GFCR optical system as well as significantly decreased measurement noise which in turn translates into the ability to detect smaller amounts of gas.
One of the most important tasks in integration of GPS/INS is to choose the realistic dynamic model covariance matrix Q and measurement noise covariance matrix R for use in the Kalman filter [2, 4].
The random variables w and v represent the process and measurement noise and it is supposed that they are white, independent noises with a Gaussian distribution.
To obtain an adequate signal margin above the measurement noise floor, it could be necessary to use a series of standard-gain horn antennas with lower antenna factors.
