A vehicle control system may include a controller that detects an object outside a vehicle, calculates an angle based on a ratio of a relative speed between the object and the vehicle to a speed of the vehicle, and updates a phase curve reflecting a phase distortion of an input signal based on the calculated angle.

An augmented reality platform and method for use of the same are provided. In one embodiment, an array of locationing devices determine a perspective value of a physical object within a space based on visual-inertial odometry, radio wave positioning, and acoustic positioning. A server determines a decided value of the physical object based on a plurality of perspective values of the physical object received from the array of locationing devices. A digital map and digital library maintained by the server maintain the location of physical objects and spatial experiential objects in order to provide the spatial experiential object to an augmented reality device.

Power saving techniques for radar-based proximity sensing can include conducting proximity scans with a radar system in an omnidirectional proximity sensing mode in which signals are transmitted without directionality. Once an object is detected within a threshold proximity, the radar system can then switch to a directional proximity sensing mode to provide accurate directional detection capabilities in a desired field of view (FOV).

A system for radio-frequency imaging of a structural environment is disclosed, including radio devices configured to transmit radio signals and a radio imaging device configured to receive the radio signals transmitted by the radio devices. The radio signals received at some times are scattered, reflected, or attenuated by an object collocated with an active localization device. The radio signals received at other times are scattered, reflected, or attenuated by the object not collocated with the active localization device. The system can obtain an indication of a location of the active localization device and, based on the radio signals received at the times the object is collocated with the active localization device, generate a radio signature of the object associated with the location. The system can then compute a score indicative of a likelihood that the object is at the location when it is not collocated with the active localization device.

Provided are a signal source space sensing method and apparatus, and an active sensing system. The method includes: a controller controls a signal transmitter to transmit a first signal to an object to be tested; the controller controls a signal receiver to receive a second signal, which is obtained after the first signal is transmitted by the object; the controller determines a coordinate relationship between the spatial position of said object and a signal source space according to the first signal and the second signal, wherein the signal source space is a coordinate space where the first signal transmitted by the signal transmitter is located; and the controller maps the second signal back to the signal source space according to the coordinate relationship between the spatial position of the object and the signal source space, to obtain a signal source space signal so as to reconstruct a sensing signal.
