摘要： The present invention includes tapered anechoic chambers and chamber systems. This invention also includes machines or electronic apparatus using these aspects of the invention. The present invention also includes methods and processes for using these devices and systems. In a preferred embodiment, a TEM antenna is utilized that is terminated by a resistive card, or R-card. This makes for a very broadband antenna that may be used to properly illuminate the test zone in a tapered chamber without changing the feed antenna. A preferred chamber utilizes an absorber layout that has never been applied to a tapered chamber, called a Chebyshev absorber layout. The concept is to place the wedge absorber tips at different heights relative to the mounting side wall and pyramidal absorber tips at different heights relative to the back wall. In this pattern, wave reflections off the pyramid tips and valleys behave very much like reflections in a multi-section transmission line. Using this Chebyshev layout around the test zone, the test zone fields will be very clean of stray signals and the polarization will be dictated by the feed horn. Also, it is then not necessary to use very thick absorber for low frequency applications, which tend to deteriorate over time. A preferred chamber also comprises a design wherein an entire tip portion of the tapered section is a separate unit. This unit is preferably designed to rotate on a system of rollers positioned between the unit and the main chamber. The result is that the polarization of the chamber can be easily changed from vertical to horizontal by simply rotating the feed structure, which can be done without disconnecting any cables to the feed.

摘要： A method for determining a physical property of an object or fluid in a dynamic multi-path clutter environment comprises transmitting an RF interrogation signal to a wireless sensor physically coupled to the object or fluid (gas or liquid) in the dynamic multi-path clutter environment, wherein the wireless sensor is operable to receive the RF interrogation signal, produce a reference signal and a measurement signal, and retransmit the reference signal and the measurement signal in the dynamic multi-path clutter environment. The reference signal and measurement signal are delayed by the wireless sensor by an amount of time that may be a function of the unknown physical property. The method also comprises receiving the retransmitted reference signal and the retransmitted measurement signal and comparing them in the time domain in order to determine the unknown physical property of the object or fluid. The method further comprises setting the time delays of the retransmitted reference and retransmitted measurement signals to be long enough for the ringdown time to be over but not so long so that the differential time is distorted by the dynamics of the system.

摘要： A region in a metallic panel that facilitates the transmission of radio frequency signals. The metallic panel may be included in a window such as the window of a vehicle or building. For example, the metallic panel may be used for heating or to reflect infrared radiation. An aperture is formed in the metallic panel to enable radio frequency signals to be transmitted through the metallic panel. The design of the aperture may be selected to enable the transmission of the desired frequency band. Furthermore, the aperture is designed such that there is a taper in the transmission amplitude and/or the phase to suppress lobing effects on the other side of the aperture. In an embodiment in which the metallic panel is used to conduct electric current, the aperture may be oriented such that the current may flow between the openings of the aperture. Accordingly, there may be uniform heating across the metallic panel without blocking the transmission of radio frequency signals in the desired frequency band.

摘要： A method for detecting an object using a transmitting antenna and an array of receiving antennas. The method comprises the step of transmitting a signal from the transmitting antenna. The magnitude and phase of a respective received signal at each of the receiving antennas is then measured. Next, the magnitude of a weighted sum of respective phase-compensated signals related to each of the receiving antennas is determined. The magnitude of the weighted sum is compared against a first predetermined threshold value and, optionally, a second predetermined threshold value. An object may be detected by considering a ratio of the magnitude of the weighted sum to the first predetermined threshold value and, optionally, to the second predetermined threshold value. In some embodiments, a second array of receiving antennas may be provided to facilitate the determination of the location of the object.
