摘要： A multi-view planar near-field scattering tomography system is provided herein. In one aspect the system is developed based on a reformulation of the signal subspace approach utilized for solving the electromagnetic inverse scattering problem. The present invention pertains to a computationally efficient approach to an electromagnetic inverse scattering-based permittivity profile estimation technique. In a second aspect, the system is developed at the millimeter-wave and THz frequency range to ensure accuracy by eliminating the multipath effects and without the need for an anechoic chamber or water as a background medium for clinical, security, and manufacturing applications.

摘要： The present invention allows for an accurate control of the electromagnetic fields inside a multimode resonant cavity in an accurate way. The multiple inputs and multiple outputs analyzer (MIMO Analyzer) features several elements such as: broadband antennas, metallic slotted plate, different types of lenses and different stirrers, both metallic and non-metallic. These elements, together with some procedures such as precise location of under-test elements out of the cavity allow for controlling the electromagnetic fields on its interior. This control permits the emulation of the behaviour of wireless communication terminals under different fading scenarios, both indoors and outdoors, and in a unique way for Rician and non-isotropic fading scenarios. Some of the elements and procedures set in the MIMO Analyzer can also be used in industrial microwave heating processes for heating, drying and curing of materials, also known as microwave ovens, allowing a greater efficiency and homogenization in the processes.

摘要： An apparatus for measuring over-the-air (OTA) wireless communication performance in an automotive application of a device under test arranged on or in a vehicle is disclosed. The apparatus comprises a chamber and a platform for supporting the vehicle within the chamber. The platform is a rotatable platform that can rotate the vehicle, and the floor is inwardly reflective, and optionally covered with a top layer to resemble asphalt or other road covers. In one embodiment, the chamber is a reverberation chamber, simulating a multi-path environment, and preferably a rich isotropic multipath (RIMP) environment. In another embodiment, the chamber has inwardly absorbing walls, simulating a random-LOS environment.

摘要： A system and method for scanning a number of frequencies in a test environment (100, 300, 400). A transmitter (112, 228, 302, 402) and a receiver (114, 228, 302, 402) are moved together to a number of locations in a scanning space (102, 200). Signals are transmitted at the number of frequencies from the transmitter (112, 228, 302, 402) at the number of locations. Reflected signals (171, 310, 412) are received by the receiver (114, 228, 302, 402) at the number of locations. The reflected signals (171, 310, 412) are reflections of the signals transmitted at the number of frequencies from the transmitter (112, 228, 302, 402). The number of locations in the scanning space (102, 200) is identified.

摘要： A radio channel generator has a radio channel model predistorted on the basis of a predetermined chamber model (98). An emulator (118) receives the weights of the radio channel model predistorted on the basis of the chamber model (98). A transmitter (122) feeds a communication signal to the emulator (118). The emulator (118) weights the communication signal with the radio channel model predistorted on the basis of the chamber model (98). The over-the-air antennas (102-116) receive the weighted communication signal and transmit it to a device under test (300). The chamber model (98) is based on a simulation or a measurement. The chamber model (98) takes into account undesired interactions in the over-the-air chamber for cancelling them during the radio channel emulation.
