摘要： A radar device comprises a radar circuit configured to transceive first radar signals that occupy a first frequency band and second radar signals that occupy a second frequency band. An antenna device of the radar device comprises a first set and a second set of antennas and is configured to selectively transduce the first radar signals via the first set and not via the second set and to selectively transduce the second radar signals via the second set and not via the first set. A processing device of the radar device detects from the first radar signals target reflections via first propagation channels and from the second radar signals target reflections via second propagation channels. The signal processing device jointly evaluates the target reflections via the first and second propagation channels to form a common virtual antenna array for determining an angular position of a target object.

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： An aircraft includes a vessel checker, an image generator, an appearance determining unit, and an information transmitter. The vessel checker identifies a suspicious vessel candidate by comparing a marine vessel detected by a marine search radar with a marine vessel transmitting data with an automatic identification system. The image generator generates an image by photographing the suspicious vessel candidate after the aircraft approaches the suspicious vessel candidate in accordance with a route for approaching the suspicious vessel candidate. The appearance determining unit determines whether the suspicious vessel candidate in the image has an appearance characteristic of a suspicious vessel. The information transmitter transmits, to an external apparatus, information indicating that the suspicious vessel candidate has the appearance characteristic of the suspicious vessel if the suspicious vessel candidate has the appearance characteristic of the suspicious vessel.

摘要： A radar object detection system includes a first sensor and a controller. The first sensor emits a first radar signal toward a first area about a vehicle, and outputs a first signal indicative of detected targets proximate to the vehicle. The controller receives the first signal from the first sensor, determines when a trailer is connected to the vehicle based on the first signal, defines a shadow-zone that corresponds to a first portion of the first area obstructed by the trailer from being viewed by the first sensor, and ignores detected targets within the shadow-zone that are indicated by the first signal.

摘要： A transponder, able to equip a cooperative target facing a Doppler radar, includes at least one receiving antenna able to receive a signal transmitted by said radar and a transmitting antenna able to retransmit a signal. The signal received by the receiving antenna is amplitude-modulated before being retransmitted by the transmitting antenna to produce a variation of the radar cross-section of the target, the variation triggering a frequency shift between the signal transmitted and the signal received by the radar comparable to a Doppler echo. The transponder applies notably to the field of radars, more particularly for collaborative systems also operating at low velocity or nil velocity. It applies for example to assisted take-off, landing and deck-landing of drones, in particular rotary-wing drones, as well as manned helicopters.

摘要： A rotating wheel of a vehicle is detected by evaluating the Doppler shift of a measuring beam, which is emitted by a detector unit passed by the vehicle, and is reflected by the wheel and returned in Doppler-shifted form. In a relative position to the wheel, the vehicle comprises an onboard unit, which can establish radio communication with a transceiver having a known location in the detector unit. The direction and distance of the onboard unit from the transceiver are measured on the basis of at least one radio communication between the same. The radiation direction or radiation position of the measuring beam is controlled in accordance with the measured direction and distance and taking into consideration the aforementioned relative position and location.
