ELECTROMAGNETIC SEARCH AND IDENTIFICATION, IN NEAR FIELD ARENAS

摘要

Sensing, in particular a generic and innovative search and identification of objects in an arena, of interest based on electromagnetic detection and/or imaging, self-focused, in the near field, with high range resolution, cross-range resolution, nearby arenas functionality, high range resolution, and accuracies, as compared to conventional solutions. Larger volume arenas can be searched with greater range resolution, accuracy, and cross range resolution as compared to conventional solutions. Embodiments include implementations sufficiently low power to be acceptable for use in human applications (for example, meeting HERP standards).

主权项

1. A method for sensing comprising the steps of:
(a) generating, for each of a multitude of resolution cells, a plurality of phase corrections, wherein each of said phase corrections:
(i) corresponds to one of a plurality of transmitter and receiver pairs, and(ii) is based on a residue of a phase difference between:
(A) a sum of distances from a given transmitter to said resolution cell and from a given receiver to said resolution cell, wherein said given transmitter and said given receiver are from said corresponding transmitter and receiver pair; and(B) a round trip distance from an element formation center to said resolution cell, wherein said element formation center is a reference point corresponding to locations of said transmitters and receivers, (b) transmitting sequentially a signal from each of said transmitters; (c) receiving a received signal in parallel with said transmitting; (d) calculating a phase corrected signal from each phase correction based on said received signal for a corresponding transmitter and receiver pair; and (e) summing said phase corrected signal for each said resolution cell to generate an emphasized object outcome.
