Abstract: According to one embodiment, a radar device comprises a panel including clusters and a controller. The controller is configured to cause a first cluster of the clusters to transmit an electromagnetic wave to a target, cause the first cluster and at least one second cluster adjacent to the first cluster to receive a reflected wave from the target, and cause the first cluster and the at least one second cluster to output a reception signal. At least one cluster other than the first cluster and other than the at least one second cluster does not output the reception signal.

Abstract: According to one embodiment, an inspection system includes an estimation device and a detection device. The estimation device is configured to estimate an inspection range having a possibility that a predetermined object is present. The detection device is configured to generate detection information as to whether or not the predetermined object is present in the inspection range.

Abstract: According to one embodiment, a radar device includes a transmitter antenna that transmits a radar signal, a receiver antenna that receives a radar echoe, an acquisition unit that acquires a plurality of pieces of first observation data having continuity, a first conversion unit that converts the pieces of first observation data into a plurality of pieces of second observation data having discontinuity, and a transfer unit that transfers the pieces of second observation data. The processing device includes a second conversion unit that converts the pieces of second observation data into the pieces of first observation data, and a processing unit that executes arithmetic processing using the pieces of first observation data.

Abstract: According to one embodiment, a wireless communication apparatus includes controlling circuitry and transmitter circuitry. The controlling circuitry is configured to divide data into bit strings by a unit of a first number of bits; add at least one padding bit to one of the bit strings according to a difference between a number of bits of the one of the bit strings and the first number of bits, when the one of the bit strings has a number of bits less than the first number of bits; add error correction codes to the bit strings to generate encoded blocks, wherein each of the error correction codes has a second number of bits; combine the encoded blocks to generate encoded frames; and aggregate the encoded frames to generate a transmission packet. The transmitter circuitry is configured to transmit the transmission packet.

Abstract: According to one embodiment, an electronic apparatus includes controller circuitry, transmitter circuitry, and receiver circuitry. The controller circuitry is configured to judge whether a payload for a first packet comprises retransmission data; set a first PHY header for the first packet, when the payload does not comprise the retransmission data; set a second PHY header for the first packet, when the payload includes the retransmission data, wherein the second PHY header comprises an amount of information larger than an amount of information of the first PHY header; and generate the first packet comprising the payload and either one of the first PHY header or the second PHY header set for the first packet. The transmitter circuitry is configured to transmit the first packet. The receiver circuitry is configured to receive an ACK signal or a NACK signal for the first packet.
