An electronic device capable of reducing a process associated with a radar search is provided. The electronic device DEVa has a transmitting linear array antenna TXA, a receiving linear array antenna RXA, and a control circuit CTLU for controlling the transmitting linear array antenna TXA and the receiving linear array antenna RXA. The transmitting linear array antenna TXA includes a plurality of transmission antennas TXr[1] to TXr[4] arranged along the Z direction, and transmits a transmission wave. The receiving linear array antenna RXA includes a plurality of reception antennas RXr[1] to RXr[4] arranged along an X direction orthogonal to the Z direction, and receives a reflected wave of a transmission wave.

In an external sensor attachment portion structure of the present invention, an external sensor includes: a sensor main body including a detection unit that detects external information; a sensor attachment bracket used to attach the sensor main body to a vehicle body frame member; and a sensor garnish including a window portion through which the detection unit is exposed in front view. The sensor garnish is provided on an outer side of the host vehicle so as to expose the detection unit of the external sensor and cover the sensor main body and the sensor attachment bracket excluding the detection unit. Small gaps are provided between the sensor main body and a window frame of the window portion in the sensor garnish. The window frame includes a noise suppression portion that suppresses wind noise due to airflow passing through the gaps along a rearward direction of the host vehicle.

Techniques are disclosed for systems and methods to provide a staggered multichannel transducer in a ranging system configured to perform remote sensing. The staggered multichannel transducer may extend in a first direction and one or more transducer elements of the array may offset from the other transducer elements in a second direction perpendicular to the first direction. The staggered arrangement of the transducer elements may improve remote sensing performance to produce accurate remote sensing data and/or imagery. The staggered arrangement also may reduce a number of transducer elements used in the transducer array which reduce the cost and complexity of the transducer array. Further, the staggered arrangement in a linear transducer array also allows for two-dimensional beam forming.

Techniques are disclosed implementing two alternative approaches for adaptive beamforming for MIMO radar. The first of these includes a “reduced complexity” iterative adaptive approach (RC-IAA) algorithm, which uses two steps including a delay-and-sum beamforming step (DAS-BF) and an IAA step that is applied to the output generated by the DAS-BF step. A second technique is described that includes a “beam space” iterative adaptive approach (BS-IAA) algorithm, which uses three steps including a delay-and-sum beamforming step (DAS-BF), a region of interest (ROI) detection step that is applied to the output generated by the DAS-BF, and an IAA step that is applied to detected ROIs.
