    • A bi-static configuration measures the time-of-flight of an RF burst using differentially-configured sampling receivers (20, 26). A precise differential measurement is made by simultaneously sampling a reference signal line and a free-space time-of-flight RF burst signal using separate sampling receivers (20, 26) having common sample timing. Two alternative sample timing systems may be used with the sampling receivers: (1) a swept delay (52) using a delay locked loop (DLL); or (2) two precision oscillators slightly offset in frequency from each other. The receiver outputs are processed (24) into a PWM signal to indicate antenna-to-antenna time-of-flight range or to indicate material properties. Applications include robotics, safety, material thickness measurement, material dielectric constant measurement, such as for fuel or grain moisture measurement, and through-tank fill-level measurement.

    • The invention relates to a sensor (1) for measuring a distance (a) from an object (2). According to the invention an oscillator (4) generates a carrier signal (5); a first modulation switch (17) modulates pulses on to the carrier signal (5) and generates a first pulse signal (3) which is emitted in the direction of the object (2); the first pulse signal (13) reflected by the object (2) and delayed by a propagation time is received; a power divider (16) positioned between the oscillator (4) and the first modulation switch (17) transmits the carrier signal (5) to a second modulation switch (19); the second modulation switch (19) modulates pulses onto the carrier signal (5) and generates a second pulse signal (9) which is delayed by a variable delay; by comparing the delay of the second pulse signal with the propagation time of the first pulse signal, means detect the propagation time and determine the distance (a) from the object (2). To increase the pass-band transmission loss of the modulation switches (17; 19) the invention provides for a third modulation switch (21) to be arranged between the oscillator (4) and the power divider (16).
