LOCATING AND RANGING USING COHERENT ARRAY RECONCILIATION TOMOGRAPHY |
摘要 |
A ranging and tracking system and method employs a Coherent Array Reconciliation Tomography (CART) approach that benefits from a series of samples gathered from deployed receivers in an area of interest, and applies a sequence of matrix operations and transformations to data defining locations in a Cartesian grid space for summing constructive characteristics in a received waveform for identifying a leading edge indicative of a time of arrival (TOA) from a signal source, and computing a metric based on the distance to the signal source. Sampled waveform information (data) from multiple locations in the area of interest allows computation of a likelihood metric for each location in the grid space of containing the signal source. Graphic rendering of the likelihood metric illustrates a position of the signal source by clustering of the locations depicting a high likelihood. |
