ABSTRACT:
A radar array linearly traverses an area of ground. Additional radar elements fore and aft of the array detect changes in elevation and orientation of the array. These elements act as a preview for the height changes due to ground variation. Any variation in height that is not detected by these fore and aft-mounted elements is thus due to variation in radar elevation and/or orientation and can be subtracted from the resulting data without introducing distortion. Correction factors are applied to the range data returned from each element in the array, which normalizes the data and makes it appear as if the array did not change orientation or elevation.
