摘要： An electronically steerable phased array and switching network connected to an FMCW radar transceiver to enable a low-cost monopulse tracking system that covers a wide field of regard using electronic beam steering. In a first mode, beamformer integrated circuits (BFICs) at each element in the array are switched synchronously with transmit/receive (T/R) switches located at the subarray level. This allows the entire aperture to be switched between transmission and reception, enabling the FMCW radar transceiver to be operated in a pulsed configuration. In a second mode, a portion of the T/R switches at the subarray level and all of the connecting BFICs at the element level are fixed in either transmitting or receiving mode, allowing separate portions of the aperture to concurrently transmit or receive. The arrangement of transmitting and receiving subarrays can be dynamically reconfigured to allow for accurate bearing and azimuth estimation using alternating monopulse.

摘要： A method for activating a function of a motor vehicle by an activation device, using a portable access device carried by a user. The activation of the function being initiated by detection of the presence of the user in a predetermined area around the vehicle, and in accordance with a result of authentication of the portable access device by the vehicle, the method including: A) the detection of the presence of the user in the predetermined area is implemented by a predetermined profile of ultra-wideband radiation emitted by the activation device in what is known as an ultra-wideband reflective mode and reflected by the user, and B) the authentication of the portable device is implemented by a bidirectional ultra-wideband communication between the activation device and the portable access device.

摘要： This document describes techniques and components of a radar system with a sparse primary array and a dense auxiliary array. Even with fewer antenna elements than a traditional radar system, an example radar system has a comparable angular resolution at a lower cost, lower complexity level, and without aliasing. The radar system includes a processor and antenna arrays that can receive electromagnetic energy reflected by one or more objects. The antenna arrays include a primary subarray and an auxiliary subarray. The auxiliary subarray includes multiple antenna elements with a smaller spacing than the antenna elements of the primary subarray. The processor can determine, using the received electromagnetic energy, first and second potential angles associated with the one or more objects. The processor then associates, using the first and second potential angles, respective angles associated with each of the one or more objects.

摘要： A radar is provided which is mechanically and functionally independent of the primary radar; applies the principles of separation of emission pattern for each interrogation of any mode; of reception pattern for each reply of any mode; of assignment of the tasks which are specific thereto to distinct units. The radar includes one or more SSR/IFF interrogators dedicated at one and the same time to SSR surveillance and to gathering new mode S targets; and includes one or more other SSR/IFF interrogators for selective surveillance dedicated to mode S surveillance and to directed interrogations of IFF identification. The radar ensures simultaneous emission of the interrogations of the SSR/IFF interrogators in different azimuths, this simultaneous emission being enabled when the azimuthal spacing of the beams formed in emission ensures a decoupled level of jamming at the level of the transponders of the aircraft between the interrogations emitted by the respective sidelobes of the beams formed in emission.

摘要： A method for processing radar signals includes emitting a first radar signal via a transmitting antenna of a first radar unit, where the first radar signal is phase modulated using a first code and a first frequency offset is added to at least a portion of the first radar signal, and emitting a second radar signal via a transmitting antenna of a second radar unit, where the second radar signal is phase modulated using a second code. The first code and the second code are orthogonal to each other and the first radar unit and the second radar unit are loosely coupled with each other. The method further includes receiving a combined radar signal via a receiving antenna of the first radar unit, where the combined radar signal comprises a reflections of the first and the second radar signals, and processing the combined radar signal at the first radar unit.
