Abstract: An active radio-frequency (RF) sensing technology for determining the relative and/or absolute state (e.g., position, velocity, and/or acceleration) of a target object (e.g., a person, a car, a truck a lamp post, a utility pole, a building) is described. The sensors described herein operate in the Terahertz band (300 GHz to 3 THz). An active RF sensing device comprises a substrate and first and second semiconductor dies mounted on the substrate. The first semiconductor die has an RF transmit antenna array integrated thereon, and the transmit antenna array comprises a first plurality of RF antennas configured to generate an RF signals having frequency content in the 300 GHz-3 THz band. The second semiconductor die has an RF receive antenna array integrated thereon, and the receive antenna array comprises a second plurality of RF antennas configured to receive RF signals having frequency content in the 300 GHz-3 THz band.

Abstract: Described herein are techniques for adapting usage of radar devices to collect data about target objects based on situational awareness data. Techniques described herein may involve selecting a radar operational configuration (e.g., waveform type, and/or transmitter and/or receiver configuration) and/or frame rate. According to various embodiments, situational awareness data may be indicative of at least one characteristic relating to a vehicle, a target object, and/or the vehicle's environment such as velocity data indicative of the velocity of the vehicle, velocity data indicative of the velocity of a target object, data indicative of at least one weather condition associated with the vehicle's environment, data indicative of the type of road in which the vehicle is traveling, data indicative of the level of traffic in the vehicle's surroundings. Techniques described herein may be deployed for use in connection with computer-assisted driving modules (e.g., ADAS and autonomous vehicles).
