A radar-enabled device that manages radar interference. In particular, the radar-enabled device detects a radar signal transmitted by a second radar-enabled device, transmits a notification of the detected radar signal, receives localization information associated with the second radar-enabled device, and sets a device location based on the received localization information. Additionally, the radar-enabled device may adjust a timing of radar signal transmissions to avoid subsequent detections of radar signals transmitted by the second radar-enabled device.

In an aspect, a first base station (e.g., Rx gNB) receives, from a radar controller, a configuration of UL T-F resources for the first base station to receive at least one radar signal from a second base station. The first base station further determines power control parameter(s) associated with the at least one radar signal, at least one UL transmission, or a combination thereof. The first base station performs, based on the power control parameter(s), action(s) to mitigate impact by the at least one radar signal to the at least one UL transmission, or by the at least one UL transmission to the at least one radar signal, or a combination thereof. The first base station measures the at least one radar signal on the set of UL T-F resources in accordance with the configuration.

This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for adapting a radar transmission based on a congestion level. A wireless device, such as a radar device, a UE, a base station, a vehicle, etc., may detect a congestion level of a wireless communication environment that includes the wireless device. The wireless device may have at least one of a first FOV or a first range within the wireless communication environment. The wireless device may transmit, based on the congestion level exceeding a threshold, a radar signal that corresponds to the wireless device having at least one of a second FOV or a second range in the wireless communication environment that is smaller than the at least one of the first FOV or the first range.

Examples disclosed herein relate to an autoencoder assisted radar for target identification. The radar includes an Intelligent Metamaterial (“iMTM”) antenna module to radiate a transmission signal with an iMTM antenna structure and generate radar data capturing a surrounding environment, a data pre-processing module having an autoencoder to encode the radar data into an information-dense representation, and an iMTM perception module to detect and identify a target in the surrounding environment based on the information-dense representation and to control the iMTM antenna module. An autoencoder for assisting a radar system and a method for identifying a target with an autoencoder assisted radar in a surrounding environment are also disclosed herein.

Certain aspects of the present disclosure provide techniques for radar detection by an apparatus. In certain aspects a method for radar detection by an apparatus includes selecting one or more radar transmission parameters based on a reference time, wherein the reference time is common to at least a group of vehicles. The method further includes performing radar detection using the selected radar transmission parameters and the reference time.

Example embodiments described herein involve techniques for orthogonal Doppler coding for a radar system. An example method may involve causing, by a computing system coupled to a vehicle, a radar unit to transmit a plurality of radar signals into an environment of the vehicle using a two-dimensional (2D) transmission antenna array, wherein the radar unit is configured to use time division multiple access (TDMA) to isolate transmit channels along a horizontal direction of the 2D transmission antenna array and Doppler coding to isolate transmit channels along a vertical direction of the 2D transmission antenna array. The method may further involve receiving, by the computing system and from the radar unit, radar reflections corresponding to the plurality of radar signals, determining information representative of the environment based on the radar reflections, and providing control instructions to the vehicle based on the information representative of the environment.

In many applications such as automobiles on busy highways, if a lot of vehicles on road are equipped with Doppler radars to help improve driving safety, no matter human-driven or auto-driven, if the radars use same frequency band, avoiding interference between them is a hard task. Assigning distinct frequencies is one of the solutions, however not only it wastes expensive spectrum resource, but also the task itself to dynamically assign frequency to vehicles randomly come together becomes a hard one to do. The disclosed invention of Doppler group radar will allow radar devices to work together using shared frequency band without interfering one another, without sacrificing performance, and without much increase in costs.

An autonomously reconfigurable surface for adaptive antenna nulling includes a lattice of electrically conductive elements (which may be embodied as crossed metallic dipoles) mounted on a thin and preferably conformal surface and aperiodically loaded with reactance tuning elements and/or RF (and typically high power) sensing circuits. Additional elements mounted on this surface include analog to digital convertors (ADCs), digital to analog convertors (DACs), and microcontroller(s). The analog outputs of the DACs are networked to reactance tuning elements via, for example, a network of thin copper traces. The analog inputs of the ADCs are networked to the RF sensing circuits via a network, for example, of thin copper traces. The digital outputs of ADCs and the digital inputs of DACs are networked to microcontroller(s) via a network, for example, of thin copper traces. An embodiment of the adaptive nulling surface can be mounted over antennas and apertures as a retrofit antenna cover or as an overlay applied to existing radomes or over a new design antenna. Once exposed to a high power radio frequency radiation, this surface determines the direction of the incident high power source and adaptively adjusts the reactance of tuning elements in the surface to reconfigure the radiation pattern of the antenna which it is covering to place a null in the direction of the interference while allowing normal operation at other angles.
