RANGE/AZIMUTH/ELEVATION ANGLE SHIP IMAGING FOR ORDNANCE CONTROL ABSTRACT Capability is provided for producing 3 scaled high resolution orthogonal image projections on a CRT of a ship under the influence of translational as well as rotational motions arising from sea state conditions, for the purpose of ship target identification and classification, and the subsequent carrying out of stand-off command weapon guidance to a designated resol- ution cell of the ship from an airborne platform. Doppler pro- cessed interferometric azimuth and elevation angle measurements of the ship scatterers derived from a coherent synthetic aperture radar are combined in a weighted multivariate regression fit using digital signal processing techniques to provide measures of ship translational and rotational motions essential to pro- viding focussed high resolution imagery and precision standoff weapon delivery to the designated ship target resolution cell. The invention also provides a capability for scaling the cross- range (doppler) dimension of Inverse SAR Profile Imagery.
