1. A method for controlling an agricultural vehicle comprising:

  • scanning a beam of wave energy through a scanning angle over a growing crop,receiving an analog signal from said growing crop,converting said analog signal to a digitized signal,analyzing the characteristics of said digitized signal to obtain information on the range of said growing crops from said agricultural vehicle and the angle of the scanning beam at a plurality of defined scan intervals,converting said range information to height data at each scan interval,extracting periodicity information from said height data,computing a steering error for said agricultural vehicle from said periodicity information after each sweep, andutilizing said steering error to control the direction of movement of said agricultural vehicle.
