Abstract

A sensor for sensing a displacement in a mechanical system using radar utilizes a miniaturized radar transceiver formed, typically, on a silicon chip. The transceiver is mounted to a fixed surface that senses a displacement of a moving surface. The moving surface is typically located in mechanical communication with a system to be sensed. By using appropriate translating circuitry, an accurate determination of the nature of displacement of the mechanical system can be made. Mechanical systems sensed can include rotating and sliding components such as motors, valves and pressure gauges. Sensors according to this invention are highly accurate and reliable.
