Coordinate Transformation for Phased Array Antenna Beam Steering Using GPS and Ship's Motion Data

Abstract

Beam steering angles of a shipboard phased array antenna are calculated, given the position of the ship, the position and attitude of the antenna on the ship, and the ship's bearing, roll, and pitch angles. The coordinate transformations were written in MATLAB; the pertinent software is added in the Appendix. An example of an application is given.
