Abstract
A method and arrangement for finding the direction to an emitter source by determining the spatial frequency of a signal received from the source in a sensor panel and comparing the spatial frequency with the instantaneous frequency. The panel includes a first matrix of sensors and a second matrix of sensors interleaved with the first matrix. The spatial frequency is determined by comparing the signals received by the first and second sensor matrices.
