Systems and methods for using auditorily-induced vection (AIV) to enhance a person's attitude awareness are provided herein. In at least one embodiment, an auditory object is projected based on the orientation of the person or a vehicle and the projected auditory is provided to the person. By projecting the auditory object, the attitude of the person or the vehicle can be conveyed to the person to enhance the person's attitude awareness.

Aspects of the disclosure are directed to apparatuses, systems and methods for radar processing. As may be implemented in accordance with one or more aspects herein, an apparatus may include receiver circuitry to receive and sample radar signals reflected from a target, and processing circuitry to carry out the following. Representations of the reflections are transformed into the time-frequency domain where they are oversampled. The oversampled representations of the reflections are inversely transformed to provide resampled reflections. Positional characteristics of the target may then be ascertained by constructing a range response characterizing the target based on the resampled reflections.

A device capable of autonomous motion includes a residual echo suppressor for suppressing echoes caused by an output reference signal. When the device outputs audio while moving with a velocity, it may receive echoes that are Doppler-shifted due to the motion. The residual echo suppressor generates estimated residual error data based on phase-shifted reference data to account for and suppress the Doppler-shifted echoes.

Certain aspects of the present disclosure provide techniques for transmitting and processing reference signals, such as DMRS, that may account for mobility characteristics (e.g., that relate to a Doppler measurement) of a wireless node (e.g., a UE), such as Doppler measurements indicating how fast such a device is moving.

The present invention discloses a planar antenna microwave module, including an oscillation circuit board and a planar antenna board. The oscillation circuit board is a double-sided printed circuit board. The planar antenna board is a double-sided PCB independent of the oscillation circuit board. PCB copper foil of the planar antenna board forms a transmitting/receiving planar antenna. The planar antenna is laminated on a bottom surface of the oscillation circuit board by using a solder joint that runs through and electrically connects two layers of PCB copper foil, and is electrically connected to the oscillation circuit board through the solder joint. The antenna boards in the present invention are of independent and separate structures, and have a small design size, a simple manufacturing process, a short production cycle, low costs, and high economic benefits.

A multiple co-frequency microwaves detection antenna includes an oscillation circuit unit, a reference ground and at least two radiation sources. The radiation sources each has a feed point and are arranged spacedly at the reference ground. A radiation gap is formed between each of the radiation sources and the reference ground. The feed point of the radiation source is electrically connected to the oscillating circuit unit.

In various examples, a radar system includes a logic circuit with an array for processing radar reflection signals. In a specific example, a method includes generating output data indicative of the reflection signals' amplitudes, and discerning angle-of-arrival information for the output data for the output data by correlating the output data with an iteratively-refined estimate of a sparse spectrum support vector (“support vector”). The approach may include: assessing at least one most probable spectrum support vector from among a plurality of most probable spectrum support vectors modeled as random values in a matrix drawn from a long-tail distribution that is controlled as a function of a scaling parameter; and update a set of parameters including a covariance estimate, the scaling parameter, and a noise variance parameter which is being associated with a measurement error for said at least one most probable spectrum support vector from a previous iteration.
