发明名称 Radiolocation system for determining the direction of incident electromagnetic waves
摘要 An antenna array for a radiolocation system, consisting of three loop antennas in mutually orthogonal planes and three dipole antennas extending along the intersections of these planes, is scanned by a pair of synchronized multplexers sequentially connecting two receiving channels to different loops and to different dipoles in a recurrent cycle. The loop and dipole voltages concurrently appearing in the outputs of the two receiving channels are fed to an analog multiplier; the resulting product, after filtering and integration, is converted to digital form and written into a memory stage assigned to the respective loop/dipole combination. The registered products are sequentially read out, in the rhythm of the scan, and are processed in a digital calculator to yield azimuthal and/or elevational data which are stored and visually displayed.
