Using the noise subspace matrix [U.sub.n], we can establish the 2D-MUSIC TOAs and AOAs spectrum function such as
Here, we have the M largest peaks of [f.sub.2D-MUSIC]([tau], [theta]) taken as the estimates of the TOAs and AOAs for the automotive targets.
Several range-based geolocation techniques have been used to estimate the target position including the time-of-arrival (TOA) [5-7], the time-difference-of-arrival (TDOA) [8, 9], the angle-of-arrival (AOA) [10-12], the received signal strength (RSS) [13-16] based techniques, or hybrid location techniques [17, 18].
Algebraic methods mainly include the TOA method  which uses the circles produced by range measurements at other sensors to find the position of the transmitter at the intersection of circles in two dimensions or spheres in three dimensions and the AOA method  which calculates the target position from the point of intersection of bearing lines.
From February 2006 to February 2016, 28 cases of TOAS
were identified from 1802 traumatic brain injury patients treated in the Department of Neurosurgery, Shanghai Changzheng Hospital.
As it turned our, TOA
has developed a mobile workforce management software that it says, among other things, allows businesses to reduce the service call window to one hour with 96 percent accuracy.
Teesside got a third shortly after when Dowson fired in from a Toas
When one unit replaces another in a theater of operations, the units must conduct a transfer of authority (TOA
) to ensure that the incoming unit is integrated seamlessly into the battle command structure and is prepared to assume the mission.
This facility enables rapid surge packing of modular Seabee Tables of Allowance (TOA
) into International Organization for Standardization (ISO) shipping containers for deployment to areas of operation worldwide or to the ships of the Maritime Prepositioned Force (MPF).
Teesside responded quickly with a ball flicked wide to Toas
whose strike drew a good save from the keeper.
