This improved model also makes it possible to evaluate the sensitivity of TOA performance to changes in the receiver hardware parameters, e.g. filter bandwidth and the threshold levels in the time-tagging process.Eng, R.Kim, Y.S.Institute of Electric and Electronic Engineer...
An ionospheric-delay correction model that measures the time of arrival (TOA) of a transionospheric electromagnetic pulse (EMP) is presented. The pulse-broadening effect due to the dispersive ionosphere is incorporated into the ionospheric group-delay model to provide an improved delay correction in ...
Time difference of arrival measurement system A method and apparatus for measuring the time difference of arrival between two received signals, each received signal being a time delayed version of a transmitted signal as intercepted at two different sensors where the transmitted sig...

Estimated time of arrival, commonly known as ETA, is a frequently used term globally to denote the time of coming. In the shipping & logistics industry, it is used to forecast when the shipment will arrive at its final port of destination. ...
With respect to the second drawback of TOA, the transmitted signal from the target node in TDOA need not contain a time stamp, since a single TDOA measurement is the difference in the arrival time at the respective base nodes. This simplifies the structure of transmitted signals and removes ...
A time of arrival measurement apparatus is used to measure the time of arrival of a radio signal transmitted by a mobile communication station operating in a wireless mobile communication network. The apparatus is provided with information indicative of a predetermined point in time at which the rad...
The time of arrival in quantum mechanics III. The measurement ensemble This paper contains further discussion of the phenomena and problems of interpretation which arise when a nonrelativistic quantum particle falls upon an ap... GR Allcock - 《Annals of Physics》 被引量: 187发表: 1969年 Average...
1)Time of arrival到达时间 1.In indoor environments,since the extremely serious Non-Line Of Sight(NLOS) and multipath condition,traditional Time Of Arrival(TOA),Time Difference Of Arrival(TDOA) and Strength of Signal(SS) based Algorithms fail to provide adequate locating accuracy.在室内环境下,针对...
This example simulates an 802.11az network consisting of a STA and multiple APs. To estimate the position of a STA, the network requires a minimum of three APs. The example simulates a ranging measurement exchange for each STA-AP pair, then trilaterates the position of the ST...
1.By analyzing the principle of hyperbolic navigation based on the time difference of arrival(TDOA),the hyperbolic navigation system,which stations are constituted of multi-ultrasonic sensors is used.通过对基于到达时间差(TDOA)的双曲线导航原理的分析,采用了基于超声波传感器的多基站双曲线定位系统。
