Sentence examples for arrival measurements from inspiring English sources

The proposed localization scheme depends on time-difference of arrival measurements calculated locally at a sensor to measure the range differences from the sensor to three anchors that can overhear each other.

The system deployment in [3] has a designated anchor Tx emitting an ultra-wideband pulse, and three anchor Rx nodes to perform the time difference arrival measurements.

This article provides the graphical properties which can ensure unique localizability in cooperative networks with hybrid distance and bearing (angle of arrival) measurements.

As noted in [7], the el-el system allows two "separate" 1-D angle of arrival measurements from two Uniform Linear Arrays to be combined.

For instance, in [8] the Cramér-Rao Bound (CRB) on location estimation accuracy of two different hybrid schemes based on the combination of RSS and either TOA or TDOA (Time Difference Of Arrival) measurements is computed, concluding that, for short-range networks, the hybrid schemes offer improved accuracy with respect to conventional TOA and TDOA schemes.

And when tracking mobile targets, frequency-difference-of-arrival measurements are often measured to cope with the Doppler effect [17, 18, 63, 64].

In [22], Moses et al. also presented a self-localization approach method using a maximum-likelihood estimator, relying on both time-of-arrival measurements and angle-of-arrival measurements.

The distances are usually obtained from the time or time-delay-of-arrival measurements using an estimated sound velocity.

With time-delay-of-arrival measurements, this error is doubled due to the two-way propagation path.

The viable methods are therefore by using time-of-arrival measurements which require strict synchronization amongst all the nodes or by two-way ranging.

In the case of time-of-arrival measurements, the difference between the measurements in opposite directions provides an indicator to the bias in the distance measurement.
