Abstract: An example multi-beam, radar based ground speed sensor utilizing a single radar integrated circuit apparatus, is provided. An example multi-beam, radar based ground speed sensor utilizing a single radar integrated circuit includes a single radar integrated circuit configured to generate frequency spectrum data and signal processing circuitry in communication with the single radar integrated circuit. The signal processing circuitry includes at least one processor and at least one memory having computer coded instructions. The computer-coded instructions are configured to, in execution with the processor, configure the signal processing circuitry to receive feedback frequency spectrum data from two or more directed frequency spectrum data beams reflecting of an obstructing surface and determine a ground speed based at least in part on the signal measurements of the returning feedback frequency spectrum data.

Abstract: A method for correcting a position of an excavation vehicle, the excavation vehicle comprising a cab, a boom, a stick, and a bucket, is provided. The method detects vehicle tilt angle data; calculates tilt-compensated position output for the boom, based on a current boom angle and the detected vehicle tilt angle data; and adjusts the position, based on the tilt-compensated position output.
