Numerous systems for reliable, low-cost, indoor, ultrasonic sensing have been demonstrated during the past few decades. Existing solutions span very low-cost transducers to high-grade equipment. This paper presents design details of a low-cost, single-tone, ranging system. A set of experimental results is included in order to evaluate consistency between ranging results obtained from receivers with various architectures. The effects of channel equalization and signal precoding evaluated show how these systems can deal with realistic reflectors.
