Abstract:
A method for efficiently compressing antenna pattern data, the antenna pattern data being a set of measured voltage data functionally dependent on angles-of-arrival; the method comprising the steps of:(a) characterizing one or more sub-element antennas where each sub-element antenna is assigned an initial polarization, a unique position, and an orientation with respect to a fixed coordinate system; (b) characterizing an idealized voltage expression for each of the one or more sub-element antennas; each idealized voltage expression being a function of a direction, polarization, and wavelength of an idealized waveform; (c) mutiplying each of the one or more idealized voltage expressions of step 1(b) by a weight variable of undetermined value; (d) expressing a reference voltage as a linear combination of the one or more idealized voltage expressions as weighted in step 1(c); (e) relating the antenna pattern data with the reference voltage of 1(d) to produce a relationship whereby the idealized voltage expressions for the one or more sub-element antennas are related to the measured voltage data as a function of the angles-of-arrival; and (f) solving for the values of the weight variables of step 1(c) by operational inversion of the relationship of step 1(e); whereby the antenna pattern data may be represented in compressed form by the values of the weight variables.
