摘要： A radio frequency distance measuring system and method where two continuous wave carrier signals, derived from a stable frequency source, are radiated from a known reference point. The frequency of the first continuous wave carrier signal is displaced from the frequency of the second continuous wave carrier signal by a selected difference frequency. When received at the unknown point, the two continuous wave carrier signals are mixed to provide a difference or beat frequency marker signal, delayed in arrival at the unknown point from the known point by the speed of light. A locally generated marker signal is derived from a stable frequency source at the unknown point, and has the same frequency as the difference frequency signal. The leading or trailing edge of the difference frequency signal can be compared with the locally generated marker signal, and the time difference or phase difference between them can be displayed using a phase meter or time interval indicator and corresponds to determine directly the distance between the known transmitter reference point and the unknown receiver point. Multiple known reference point transmitters, each transmitting two continuous wave carrier signals displaced in frequency by a selected difference frequency, can be used to obtain two or more distance measurements at the unknown point to determine the position of the unknown receive point with respect to the known transmitter points. A chart shows the relationship of the selected difference frequency to the distance that can be measured without ambiguity.

摘要： An improved apparatus for generating a stable frequency signal is disclosed. A master oscillator provides an output signal having a preselected frequency value X. A main feedback loop, a first feedback loop and a second feedback loop are provided. Deviation of the output signal from the preselected frequency value X causes the second feedback loop to be responsive at twice the frequency rate as that of the first feedback loop. The frequency difference between the values of the first feedback loop and the second feedback loop is used to produce a control signal for the main feedback loop used to control the frequency value X of the output signal. The circuit is self-correcting and exhibits high order short and long term stability. Two embodiments are disclosed.

摘要： A distance-measuring receiver and system uses a transmitter which transmits only a single continuous-wave signal. The receiver produces a first component and a second component from the received signal. The first component is frequency doubled and used to produce a signal indicative of the beginning of a measurement window. The second component is used to produce a signal indicative of the end of the measurement window. The size of the measurement window can be used to produce a real time indication of the position of the receiver form the transmitter.

摘要： A distance measuring receiver system and method for determining the distance of a receiving station from a transmitting station, which provides the distance information by the reception and processing of a pair of signals (preferably continuous wave carrier) transmitted by the transmitting station. The filter subsystem 106 supplies the upper signal to the first channel 501 and the lower signal to the second channel 502 of a lane expansion subsystem 108, which produces a plurality of difference frequency signals 113, 115, 117, 119 (of preselected multiples) in accordance with the upper and lower signals. A reference subsystem 112 in accordance with the oscillator signal 121 supplies a plurality of reference signals 127, 129, 131, 133 (having frequencies equal to the frequencies corresponding to difference frequency signals). By comparing the phase of corresponding difference frequency and reference signals, phase comparator subsystem 114 produces a plurality of measurement lanes of different lengths, which allow the present invention to zero in on the position of the receiving station. Substantial elimination of phase error to each signal caused by signal processing is achieved by the present invention.

The input terminal is formed by connecting together the first end of each inner conductor, the first ends being present at a first opening in the housing. The second ends of the inner conductors, which are all present at a second opening in the housing, are connected together outside the housing by (n-1) number .lambda. lines so as to form an electrical wheel. Each end at the second opening is an output terminal of the power splitter. A power combiner is disclosed for summing at an output terminal R.F. power applied to n number input terminals, where n.gtoreq.2 and is an integer, irrespective of the impedances at the input or output terminals. The power combiner utilizes n number .lambda./4 inner conductors disposed in a .lambda./housing, which provides a common electromagnetic shield. The first end of each inner conductor present at a first opening in the housing is an input terminal. The output terminal is formed by connecting together the second ends of each inner conductor present at the second opening in the housing.
