Automatic control systems have the ability to greatly improve modern agriculture, [1], by increasing efficiency, allowing greater precision, and by decreasing the associated costs. Sugar cane harvesting is one activity that has a need for such systems. In particular, control of the harvester’s “base-cutter” height can greatly improve the harvesting efficiency and reduce the amount of extraneous matter reaching the mill. This paper investigates the feasibility of an electronic sensor, based on microwave technology, to accurately sense ground level and hence control the harvester base-cutter. The microwave sensing technique studied uses a transmission style sensor that measures the amplitude of an electromagnetic wave propagating from one side of the row of cane to the other. Results show that an operating frequency between 2 and 4 GHz, transmitted using a 9.5dB gain antenna, is best suited to this application.
