Localization

Time of arrival and time-difference of arrival estimation, time-of-arrival positioning, generalizer cross-correlation, device and target positioning

This section contains applications that perform object localization and tracking in radar, sonar, and communications. Localization could encompass active or passive scenarios. Techniques include time of arrival and time difference of arrival measurements.

Featured Examples

Source Localization Using Generalized Cross Correlation

Determine the position of the source of a wideband signal using generalized cross-correlation (GCC) and triangulation. For simplicity, this example is confined to a two-dimensional scenario consisting of one source and two receiving sensor arrays. You can extend this approach to more than two sensors or sensor arrays and to three dimensions.

Locating an Acoustic Beacon with a Passive Sonar System

Simulate a passive sonar system. A stationary underwater acoustic beacon is detected and localized by a towed passive array in a shallow-water channel. The acoustic beacon transmits a 10 millisecond pulse at 37.5 kilohertz every second, and is modeled as an isotropic projector. The locator system tows a passive array beneath the surface, which is modeled as a uniform linear array. Once the acoustic beacon signal is detected, a direction of arrival estimator is used to locate the beacon.
