Abstract
A method and apparatus for controlling a radar beam emitted by a radar sym. The invention produces improved high resolution ground mapping by aligning the antenna isogain or isonull lines with the ground radial lines. The antenna axis is rolled by an angle determined from the geometric principles of the unit vectors along the ground radial lines. A new azimuth pointing angle is then computed and implemented. A new azimuth beamshape, azimuth beamwidth and azimuth beam spoiling factor are also computed and implemented.
