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.

W(k) is M-dimension process noise vector, V(k) is N-dimension measurement noise vector, W(k) as well as V(k) can be modeled as Gaussian white noise and satisfy the following normal distribution:
Equivalent measurement noise [[bar.[eta]].sub.k] is a Gaussian white noise with zero mean and covariance matrix [[bar.R].sub.k] = E{[[bar.[eta]].sub.k] [[bar.[eta]].sup.T.sub.k] = ([[bar.[R]].sup.i,j,sub.k]), and we further have
Since physiological signals are prone to measurement noise and capricious artefact, advanced signal processing is necessary to improve signal quality.
In this paper, the process noise [w.sub.n] [member of] [R.sup.q] and measurement noise [mathematical expression not reproducible] are assumed to be correlated white noises with zero mean and
where d(p) = [([d.sub.1](p), [d.sub.2](p), ..., [d.sub.i](p), ..., [d.sub.N](p)).sup.T] is the vector of real distances between the vehicle and transponders [mathematical expression not reproducible] is the measurement of d(p); w represents the measurement noise vector which cause ranging errors; COV = diag([[sigma].sup.2.sub.1], [[sigma].sup.2.sub.2],..., [[sigma].sup.2.sub.i], ...
A suitable selection of process noise and measurement noise covariance matrices is important in EKF estimation.
where W is the system noise, v is the measurement noise, G is the system noise driving matrix, and y is the vector of the measurement value.

The approach in that paper is rather weak in the presence of unknown measurement noise. Therefore, the state estimation problem of JMS for target tracking systems in the presence of unknown noise and steering command is an interesting topic to pursue.
