摘要： In one embodiment, a method includes providing instructions to broadcast a modulated radar chirp signal from a radar antenna of a vehicle. The modulated chirp signal includes data associated with the vehicle. The method includes receiving a first return signal whose waveform substantially matches the modulated chirp signal. The first return signal is the modulated radar chirp signal after reflecting off of an object in an environment surrounding the vehicle. The method includes calculating a location for the object using the first return signal, receiving, from a base station antenna, a second return signal that indicates the modulated chirp signal was received by the base station antenna, and providing instructions to establish a wireless communication session with the base station antenna.

摘要： A ranging and positioning system comprising transmitters and receiver nodes communicating together by chirp-modulated radio signals, that have a ranging mode in which ranging exchange of signals takes place between a master device and a slave device that leads to the evaluation of the range between them. The slave is arranged for recognizing a ranging request and transmit back a ranging response containing chirps that precisely aligned in time and frequency with the chirps in the ranging requests, whereupon the master can receive the ranging response, analyze the time and frequency the chirps contained therein with respect to his own time reference, and estimate a range to the slave.

摘要： The present invention relates to a radar device and a frequency interference cancellation method thereof, and arranges a configuration comprising: an antenna unit for transmitting a radar transmission signal to a periphery and receiving a signal reflected from a target; an RF unit for generating the transmission signal, converting frequencies of a transmission signal and a reception signal, and amplifying a reception signal; a signal processing unit for generating a control signal to generate the transmission signal and cancelling frequency interference from a reception signal of the RF unit; and a control unit for generating radar detection information by using an output signal of the signal processing unit, and tracking information by accumulating the radar detection information. The present invention enables real time changing of a hopping pattern according to a radar frequency interference environment, thereby achieving operation of the hopping pattern adaptively optimized to the frequency interference environment.

摘要： One embodiment of the present invention relates to a transmitter within a single integrated chip substrate, which is capable of continuous beam steering of a transmitted radar beam as well as an option to change the physical position of the origin of the transmit radar beam. The transmitter has a signal generator that generates an RF signal. The RF signal is provided to a plurality of independent transmission chains, which contain independently operated vector modulators configured to introduce an individual phase adjustment to the high frequency input signal to generate separate RF output signals. A control unit is configured to selectively activate a subset of (e.g., two or more) the independent transmission chains. By activating the subset of independent transmission chains to generate RF output signals with separate phases, a beam steering functionality is enabled. Furthermore, the subset defines a changeable position of the transmitted radar beam.

摘要： The present invention relates to a lidar measurement system for the detection of the presence and/or motion of particles and/or objects in a space region remote from the lidar measurement system and comprising an interferometer arrangement, as well as to a corresponding method using such a measurement system. The interferometer arrangement comprises a continuous wave laser source (2), a photodetector arrangement (7), and optical components which are adapted to split light (23) emitted by the continuous wave laser source (2), to guide it along a first optical path constituting a measurement branch (4) and along a second optical path, which is separate from the first optical path and constitutes a reference branch (5), and to eventually have it incident in a spatially coherently superimposed manner onto the photodetector arrangement (7). The reference branch (5) has a predetermined optical path length, and the measurement branch (4) comprises a measurement portion (16), in which the light is directed away from the measurement system towards a space region remote from the measurement system and passes through the space region and light backscattered towards the measurement system by particles present in the space region is received again at the measurement system. Further, an evaluation unit (9) is provided which is coupled to the photodetector arrangement (7) and is adapted to receive the detector signal thereof and to determine from the detector signal the presence and/or movement of particles in the remote space region. The continuous wave laser source (2) has a coherence length in the range of 0.1 to 100 m.

摘要： A sensing system (11) includes a first radar sensing assembly (10; 3104, 3106; 4100, 4200) and an analysis system (18). The first radar sensing assembly (10; 3104, 3106; 4100, 4200) measures plural distances (12; 22, 30; 42, 50, 60, 70, 80; 4102, 4202) to a first target location (16) at different times using radar. The analysis system (18) receives the plural distances (12; 22, 30; 42, 50, 60, 70, 80; 4102, 4202) from the first radar sensing assembly (10; 3104, 3106; 4100, 4200) and quantifies movements of a target object (14) at the first target location (16) at the different times by calculating differences in the plural distances (10; 3104, 3106; 4100, 4200) measured by the first radar sensing assembly (10; 3104, 3106; 4100, 4200). The analysis system (18) generates one or more first quantified activity level values indicative of the movements of the target object (14) at the first target location (16) using the differences in the plural distances (12; 22, 30; 42, 50, 60, 70, 80; 4102, 4202) that are calculated.

摘要： An I/Q mixer and processing method for a radar system include an RF input and an LO input. Phase shifters apply a selectable phase shift to the LO signal to produce a first phase-shifted version of the LO signal and a second phase-shifted version of the LO signal, the first and second phase-shifted versions of the LO signal being in quadrature. A first set of switches is controllable to selectively apply the selectable phase shift to the LO signal. A first mixer unit receives the RF signal at a first input of the first mixer unit, and a second mixer unit receives the RF signal at a first input of the second mixer unit. A second set of switches is controllable to apply one of the first and second phase-shifted versions of the LO signal to one of a second input of the first mixer unit and a second input of the second mixer unit and to apply the other of the first and second phase-shifted versions of the LO signal to the other of the second input of the first mixer unit and the second input of the second mixer unit. A counter generates a count for sequencing through states of the first and second sets of switches.
