摘要： Data compression method, system, and program code for compressing antenna pattern data generated by measuring the complex voltage derived from the interaction of a RF waveform and a sensing element are disclosed. The antenna pattern data are modeled with a plurality of infinitesimal antenna elements, each element defined in terms of a distinct position, orientation, and polarization. An analytical expression for the interaction between the plurality of infinitesimal antenna elements and an impinging waveform yields a plurality of expressions for a theoretical voltage. The plurality of infinitesimal antenna elements constitute a mathematical basis set from which a weighted linear combination is constructed. The value of the weights are determined by equating the complex voltage representing the antenna pattern data with the theoretical voltage representing the plurality of weighted infinitesimal antenna elements. In turn, the weights comprise an encoded representation of the antenna pattern data from which the antenna pattern data may be reconstructed or decompressed.

摘要： A method for resolving the angular ambiguity inherent in the differential phase measurements of a source of electromagnetic signal by an interferometric system of antenna elements. Three or more independent differential phase measurements are acquired between predetermined pairs of antenna elements. The ambiguous solutions to each of the differential phase measurements are represented as a group of equally-spaced, parallel lines. The points of intersection between two groups of lines represent ambiguous solutions to the system of equations from which the true angles-of-arrival may be determined. The set of ambiguous solutions is evaluated using the remaining differential phase measurements. The most probable solution to the system of equations is determined by minimizing cost functions with the following embodiments: tightest cluster of intersecting lines; maximum likelihood estimation; and voltage reconstruction comparisons with measured voltages.
