摘要： An antenna system for at least one of Elint and Sigint, configured to detect weak electro-magnetic signals, comprises an antenna and a feed manifold, which comprises a plurality of feeds located on a focal surface of the antenna. The antenna is configured to function as a two-dimensional focusing element, having spherical symmetry. The system is configured such that a planar wave-front associated with a electro-magnetic signal, that is impinging on the antenna, is focused by the antenna to a feed, situated at a distance from the antenna corresponding to a focal distance of the antenna along a propagation vector of the wave-front. The spatial field of view of the antenna system is based on a number of feeds and the spacing between feeds. This produces, for each feed, a respective high-gain beam, with direction along the line connecting the center of the spherical symmetry and the feed.

摘要： A calibration utilizes reference data indicative of a position of a target element relative to a reference location, of a position of a reference point on a rotatable support relative to the reference location, orientation data indicative of at least one angular position of the rotatable support, and antenna measurement data indicative of electromagnetic echo signals received by a radar antenna from the target element. A measured position of the target element relative to the radar antenna is determined based on at least a portion of the antenna measurement data. A reference position of the target element relative to the radar antenna is determined based on the reference data and on at least a portion of the orientation data. At least one bias value or function associated with the orientation data and/or the antenna measurement data is determined based on a deviation between the determined measured position and reference position.

摘要： A method and system are presented for determining properties of an electromagnetic waveform. The method comprises: providing measured parametric EM field data indicative of measured vector components of electric and magnetic fields of an EM waveform measured in at least one instance of time; providing reference data indicative of a plurality of reference data sets, each data set comprising: a reference steering vector parameters indicative of a certain respective direction of arrival (DOA), and a corresponding parametric EM field reference data including reference vector components of an electric and magnetic field pertaining to a wavefront propagating with the DOA of the corresponding reference steering vector parameters; determining a matching score between the measured parametric EM field data and the parametric EM field reference data of one or more of the reference data sets; and in case the matching score of a certain reference data set complies with a certain threshold condition, determining that said measured parametric EM field data corresponds to said EM waveform having a single EM wavefront thereby enabling to discriminate between measured EM waveforms having a single wavefront and measured EM waveforms having multiple wavefronts.
