Abstract
Using an electronically scanned phased array antenna, a technique is developed for aligning a broad elevation beam along an isodop for use in synthetic aperture mapping. A beam steering controller algorithm for practical implementation of the technique is described. Implementation is realized by means of a beam steering controller and the radar computer. The controller first finds the space stabilized row and column for a given phase shifter. A look-up table furnished by the radar controller provides a slope correction as a function of row. The slope is multiplied by the element column to give the correct linear phase function. This term is then subtracted from the term used to point the beam peak.
