Abstract: 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.

Abstract: A linear chirp radar system, apparatus and method use a radar control processing unit to control an LFM radar front end which includes a frequency-scanning transmit antenna and a frequency-scanning receive antenna which respectively sweep a transmit and receive energy focus across an angle space with each linear chirp signal, where the radar control processing unit processes digital output signals generated from target return signals received in response to transmitted linear chirp signals and extracts target range-angle information by applying time-frequency analysis processing to the digital output signals to generate a first range-angle map which includes range-biased angle information, and then applying a group delay compensation process to generate a second range-angle map which includes target range-angle information that is generated by selectively adjusting the range-biased angular information in the first range-angle map with an angular adjustment.

Abstract: Aspects of the present disclosure are directed to radar communications with disparate pulse repetition intervals, as may be implemented with radar transmission, receiver and processing circuitry. As may be utilized in accordance with one or more embodiments herein, time division multiplexing (TDM) multi-input multi-output (MIMO) radar signals are transmitted by transmitting sets of successive radar signals, each set having a pulse repetition interval (PRI) that is different than the PRI of sets of radar signals transmitted in another one of the sets. Positional characteristics of a target may be ascertained based on the PRI used in each of the sets and on phase characteristics of ones of the radar signals reflected from the target.

Abstract: Aspects of the present disclosure are directed to radar signal processing apparatuses and methods. As may be implemented in accordance with one or more embodiments, digital signals representative of received reflections of radar signals transmitted towards a target are mathematically processed to provide or construct a matrix pencil based on or as a function of a forward-backward matrix. Eigenvalues of the matrix pencil are computed and an estimation of the direction of arrival (DoA) of the target is output based on the computed eigenvalues.

Abstract: Aspects of the present disclosure are directed to radar and radar processing. As may be implemented in accordance with one or more embodiments involving multi-input multi-output (MIMO) co-prime radar signals transmitted by a plurality of transmitters and reflected from at least one target, the reflected radar signals are processed by resolving ambiguities associated with a range-Doppler detection based on unique pulse repetition frequencies (PRF)s associated with respective chirp groups of the reflected radar signals. Phase compensation is applied to compensate for motion-induced phased biases and, thereafter, Doppler estimates are reconstructed to provide a dealiased version of the reflected radar signals.

Abstract: A distributed aperture radar system, apparatus, architecture, and method are provided for generating a completed virtual array aperture by using a radar control processing unit to construct a sparse forward-backward matrix from one or more sparse measurement array vectors and to generate beamforming outputs of a completed virtual array aperture by performing forward-backward matrix completion processing of the sparse forward-backward matrix to construct a completed forward-backward matrix by filling holes in the sparse MIMO virtual array aperture to suppress spurious sidelobes caused by holes in the sparse forward-backward matrix, thereby enabling computation of one or more super resolution direction of arrival (DoA) estimation values based on the completed forward-backward matrix.

Abstract: A vehicle radar system, apparatus and method use a radar control processing unit to control an RF transmitter unit to generate a radiated beam by a long and medium range radar (LMRR) beam shaping antenna array which has a range coverage pattern with more power concentrated along a central direction axis for long range detection and less power spread off to sides of the central direction axis for medium range detection, wherein the LMRR beam shaping antenna array includes a plurality of transmit radiator elements stacked over a power dividing feeding network and separated by a conductive coupling aperture layer comprising a plurality of coupling apertures such that each transmit radiator element is aligned through a corresponding coupling aperture to a corresponding feeding line conductor from the power dividing feeding network.

Abstract: A radar system includes a processor and a non-transitory computer-readable medium storing machine instructions. The processor obtains an ego velocity Vego of a radar system, a range R of an object in an environment of the radar system, and a radial velocity Vr of the object. The processor determines a simplified two-dimensional (2D) angular search grid and performs a grid-based direction-of-arrival algorithm using the simplified 2D angular search grid. In some implementations, the processor determines a ring of possible positions for a stationary object based on the ego velocity Vego, the range R, and the radial velocity Vr, and includes the ring of possible positions in the simplified 2D angular search grid. In some implementations, the processor determines an arc of possible positions for a moving object based on the range R, and includes the arc of possible positions in the simplified 2D angular search grid.
