"higher resolution requires physically or effectively larger apertures... dramatically increasing effective aperture of remote radio-frequency monitoring system simply by tying rotating antenna to flat sparse array...  stitches together data from at least 3 antennas: 1D sparse antenna on 2D plane, and 2 antennas attached to either end of tether rotating at right angle to plane... effectively create an aperture area much larger than sum of physical components... faster cycle time.. numerous applications, including ground moisture monitoring"
