  • Patent number: 10776653
    Abstract: A System and a method for processing at least two M-dimensional data-measurements (DMs) of a physical-property for detecting one or more new-objects and/or a transition of one or more known-objects, in complex constant-background DMs, using at least one processor and at least one memory element, the method comprising: generating a filtered-new-DM by match-filtering a new-DM, respective to impulse response of a reference-DM; generating a filtered-reference-DM by match-filtering the reference-DM, respective to impulse response of the new-DM; generating an M-dimensional object-indicator (OI) by subtracting the filtered-reference-DM from the filtered-new-DM, or vice versa; and generating an M-dimensional data score (DS) from the M-dimensional OI, where each of the scores is a probe for existence of an object at a specific M-dimensional location.

  • Patent number: 9998198
    Abstract: A method for detecting a dispersed pulse in a received signal that has been dispersed by a dispersive medium includes obtaining an input array of cells, each indicating an intensity of a frequency component of the signal at a representative time. A fast dispersion measure transform (FDMT) is applied to concurrently sum the cells of the input array that lie along different dispersion curves, each curve defined by a known non-linear functional form and being uniquely characterized by a time coordinate and by a value of the dispersion measure. Application of FDMT includes initially generating a plurality of sub-arrays, each representing a frequency sub-band and iteratively combining pairs of adjacent sub-arrays in accordance with an addition rule until all of the initially generated plurality of sub-arrays are combined into an output array of the sums, in which a cell of the output array that is indicative of a transmitted pulse is identified.

  • Publication number: 20150362737
    Abstract: An imaging method and system are provided, being particularly useful for imaging a relatively wide field of regard on a relatively small detection surface with high spatial resolution. The method comprises: creating a segmented image of a field of regard in an effective object plane, said image being formed by an array of N image parts of the field of regard; and projecting a selected number M?1 of patterns of structured light onto a detection surface, which is located in a plane conjugate to the effective object plane and has geometry and size substantially of the image part, each of the M patterns being formed by selected K light components of said N image parts concurrently projected onto the entire detection surface forming a superposition of the K image parts, thereby enabling reconstruction of the image of the field of regard from detected number M of patterns of the structured light.
