Modular multi-angle synthetic aperture radar sensor on a track

A synthetic aperture radar sensor system comprising:

• a gimbal;
• a plurality of segments defining a longitudinal axis, the plurality of segments mechanically coupled to the gimbal so the plurality of segments may be rotated about a central vertical axis perpendicular to the longitudinal axis and may be rotated about the longitudinal axis;
• a plurality of antennas, each antenna coupled to a separate one of the plurality of segments and adapted to move along the longitudinal axis formed by the plurality of segments so the plurality of antennas may move relative to each other along the longitudinal axis, each antenna adapted to at least one of transmit or receive a corresponding radio frequency signal;
• and
• wherein the synthetic aperture radar sensor is adapted for one or more of high-gain synthetic aperture radar operation, altimetry operation, moving target indication operation, monopulse operation, pulse repetition frequency operation, side-looking operation, vertical-looking operation, interferometric synthetic aperture radar operation, or terrain point cloud operation.
