Abstract: A radar packaging component including a coating affixed on a substrate. The coating includes a binder and a plurality of acicular flake particles dispersed in the binder. The acicular flake particles exhibit a length and the length of at least 30 percent by volume of the acicular flake particles is oriented in a first axis. A vehicle includes a radar packaging component and a radar sensor positioned under the radar packaging component.

Abstract: A radar sensor system includes transmit circuitry configured to provide a source signal to first and second transmit antenna slots, selectively shift a phase of the source signal as provided to the second transmit antenna slot relative to the source signal as provided to the first transmit antenna slot, and output transmit signals based on the source signal provided to the first and second antenna slots. Receive circuitry is configured to receive, via first and second receive antenna slots, reflected signals corresponding to the transmit signals as reflected from an object in the environment. A control module is configured to, in a first antenna pattern mode, sum the reflected signals, and, in a second antenna pattern mode, calculate a difference between the reflected signals. The radar sensor system is configured to detect the object based on the sum of the reflected signals and the calculated difference between the reflected signals.

Abstract: A radar sensor system includes an antenna module configured to generate an array of real signal measurements that correspond to signals transmitted from first antennas arranged on the antenna module, reflected from an object in the environment, and received by second antennas arranged on the antenna module, and a virtual array (VA) estimation module configured to generate a VA including the real signal measurements and a plurality of virtual signal measurements that correspond to locations in the VA between the real signal measurements and generate, based on the VA, detection data indicative of the object in the environment.

Abstract: A radar system includes a controller is operable to receive a first signal from a first antenna and a second signal from a second antenna arising from the reflection of the first pulse by an object located in the radar field-of-view. The controller is also operable to calculate, before reception of the reflection of the second pulse by the object is finished, a first transformation of the first signal and the second signal to determine range-data based on the reflection of the first pulse. The range-data includes a phase-component and an amplitude-component. The first transformation is followed by calculate a complex non-coherent integration of the phase-component and the amplitude-component to determine averaged-range-data that includes a Doppler-phase and a Doppler-amplitude.
