Abstract: There is provided a imaging device including: an N-type region formed for each pixel and configured to perform photoelectric conversion; an inter-pixel light-shielding wall penetrating a semiconductor substrate in a depth direction and formed between N-type regions configured to perform the photoelectric conversion, the N-type regions each being formed for each of pixels adjacent to each other; a P-type layer formed between the N-type region configured to perform the photoelectric conversion and the inter-pixel light-shielding wall; and a P-type region adjacent to the P-type layer and formed between the N-type region and an interface on a side of a light incident surface of the semiconductor substrate.

Abstract: The present invention includes: a transmitter/receiver 20 that transmits an FMCW modulated sweep signal at least twice; an FFT unit 32 that performs Fast Fourier Transform on the at least two sweep signals received in response to the transmission from the transmitter/receiver; and an MRAV processor 35a that calculates ranges and velocities of multiple targets by calculating beat frequencies corresponding to at least two sweeps by the transmitter/receiver based on the at least two sweep signals obtained by the Fourier Transform performed by the FFT unit, calculating velocities based on a frequency difference and a time difference of the calculated beat frequencies, and calculating ranges based on the calculated velocities and beat frequencies.

Abstract: The present invention includes: an antenna 10 including an element 11a for use in both transmission and reception that is divided into a first transmission/reception element and a second transmission/reception element, and an element 12a for reception only that is divided into a first only-reception element and a second only-reception element; a beam shaping unit 34 that divides an angle region to be observed into a plurality of regions, and forms transmission beams by using the respective elements of the antenna so that the divided angle regions are covered by the transmission beams, and in reception, sets aimed beam direction of each element of the antenna to be the same as that of the first transmission/reception element, and that of the second transmission/reception element, forms phase monopulse beam of ? and ? by using the first transmission/reception element and the first only-reception element, and the second transmission/reception element and the second only-reception element to cover each of the plu

Abstract: The present invention includes a transmitter/receiver 20 that transmits/receives an FMCW based sweep signal, a velocity grouping unit 36 that performs grouping of a target for each velocity range by a velocity of the target calculated based on the sweep signal from the transmitter/receiver, and a correlation tracking unit 37 that performs correlation tracking for each velocity group which is grouped by the velocity grouping unit.
