摘要： A time space coherence interferometer (TSCI) system is provided. In one embodiment of the present invention the TSCI system includes an interferometer in communication with an RF source and a receiver. The interferometer includes a first switch, a second switch, a transmit element, a receive element and a sequencer circuit, wherein the sequencer circuit is configured to alternate the first and second switches between first and second configurations. In a first configuration, the signal from the RF source is provided to the transmit element, where it is communicated to the receive element via a signal path, and provided to the receiver. In the second configuration, the signal from the RF source is provided to the receiver via a reference path. The switching sequence results in a complex ratio of the signal path signal to the reference path signal (e.g., an S21 transmission ratio) being provided to the receiver.

摘要： A direction-determining system, particularly for measuring the elevation by determining the transit-time differences of electromagnetic waves which are successively sent out by a reference radiator and a plurality (n) of radiators arranged along a straight line. From the n values for the transit-time differences, the azimuth ( phi ) is calculated by means of a computer in two different ways: the first serves to determine an elevation of less than 3*, and the second serves to determine an elevation of more than 3*.

摘要： A novel radio communication system is disclosed, the system having particular applicability and utility as a radio navigation aid. A transmitting means is utilized which, in the preferred inventive embodiment, comprises a plurality or array of antennas disposed in fixed spaced-apart relationship with one another at a known location. One of the transmitting antennas transmits a reference signal, preferably a carrier wave, modulated by a first frequency or frequencies. The remaining transmitting antennas each transmits a single or double sideband suppressed carrier signal produced by respectively different modulating frequencies for each signal. These different modulating frequencies bear a harmonic or multiple relationship with the first modulating frequency or frequencies. In the preferred inventive embodiment, each of the remaining transmitting antennas are disposed at different distances from the first or reference transmitting antenna. The novel system further includes receiver and signal processing means disposed either at the same or different locations remote from the location of the transmitting means. The receiver means generates from the received reference signal a signal having the frequency and phase of the first modulating signal at the transmitter. From this signal, the other modulating signals coherent with the first signal are derived. The receiver/signal processing means derives from the other received signals the second, third, and fourth modulating signals, and compares the phases of the signals of like frequency. In an alternative embodiment wherein the receiver means and signal processing means are disposed at different remote locations, and each receives the signals transmitted by the transmitting array, the receiver means serves only to detect the various modulating frequencies, and then retransmits the detected frequencies to the signal processing means for phase comparison. In each instance, the detected phase differences are indicative of the relative angular direction of the receiver means from the transmitting array. In the preferred embodiment, the antennas of the transmitting array are disposed on a line and the phase difference detected represents the angular deviation of the receiver from a plane bisecting and perpendicular to the line of transmitting antennas. The accuracy of the system is determined by the maximum spacing between a pair of antennas in the array. The other antennas are used only for resolving ambiguities.

摘要： A system and method of improving data link performance between two or more wireless data transceivers includes: clipping and inverting the data components of a communication signal which are calculated to cause non-linear saturation effects in the downstream power amplifier; delaying a first time series to align the first time series with the clipped and inverted data components of a second time series; adding the clipped and inverted data components of the second time series to the delayed first time series to obtain a modified composite waveform; creating a sacrificial band containing principal energy of the clipped and inverted data components of the second time series; combining the sacrificial band to the modified composite waveform in non-overlapping signal space to obtain an optimized composite waveform; and amplifying the optimized composite waveform with the downstream power amplifier of one or more of the two or more wireless data transceivers.
