Title: Frequency modulation distance measurement of active target
Inventor: DAVIES RICHARD
IPC: G01S13/82
Filed: 1990-04-27
Abstract: A technique for short range distance measurement using sub-microwave radio frequency signals in which the distance between a measurement unit and a co-operative active target unit is determined as follows: The measurement unit transmits a carrier signal which is frequency modulated with a low frequency modulation signal. This is received by the target unit which applies a small frequency shift to the signal and re-transmits it. The measurement unit receives the frequency shifted signal and mixes it with its transmitted signal to form a further frequency modulated signal in which the carrier frequency is equal to the frequency shift applied by the target unit and the modulation signal is at the frequency of the transmitter modulation and takes a form dependent on the round trip delay between measurement and target units and hence distance. The nature of the dependence is determined by the modulation waveform. If this is sinusoidal, the modulation amplitude is directly proportional to distance. By measuring this amplitude the distance can thus be determined. As a result of the frequency shift in the target unit, forward and return paths can be separated and therefore operation at sub-microwave radio frequencies is possible. <IMAGE>

Abstract: PCT No. PCT/GB90/00924 Sec. 371 Date Jan. 29, 1992 Sec. 102(e) Date Jan. 29, 1992 PCT Filed Jun. 15, 1990 PCT Pub. No. WO90/15972 PCT Pub. Date Dec. 27, 1990.Color changes in a target, such as a chemical sensor using a colorchanging indicator reagent to detect the presence of a poisonous gas, are continuously monitored by reflecting the target (10) on to a sensor (16) light originating from first one and then another light source (12a, 12b, etc), each having a different, known emission wavelength. In each cycle, direct light from the appropriate source is also collected by another sensor (14), connected in a closed loop (26) with circuitry in which the emission intensity is compared with a known reference value (38) and which adjusts the emission intensity so as to stabilize it at this constant reference value. Once this is stabilized, the reflected light intensity signal is passed to a data store (20), after which a divider (22) produces an output signal (36) representing the ratio of the reflected light intensities in two separate cycles originating from two different light sources (12a, 12b, etc). The conduct of each cycle is controlled by timing means (18). Where there are two light sources, the wavelength of the second (12b) is outside the response range of the target, that of the first (12a) being at or near the peak target response, so that all the divider output signals represent successive values of actual reflected light intensity. These signals can be processed to show the rate of color change in the target and used to operate e.g. an alarm.
