Abstract: A transmitting array antenna includes a second antenna group placed in a position inside a first antenna group in a first direction and a position different from the first antenna group in a second direction. A receiving array antenna includes a fourth antenna placed in a position outside a third antenna group arranged in the first direction and a position different from the third antenna group in the second direction. An interelement spacing between a receiving antenna of the third antenna group located at an end on a second side is identical to an interelement spacing in the first direction between a transmitting antenna of the first antenna group on the first side and each of the second antenna group. In a case where the first antenna group and the third antenna group are identical in position in the second direction, positions of antennas are different.

Abstract: In a direction estimator, a horizontal array maximum likelihood estimator calculates first maximum likelihood values corresponding to NW angles in a first direction by performing a maximum likelihood estimation process on the first direction using signals received by a first virtual linear array and extracts first candidate angles of arrival of incoming waves in the first direction. A vertical array maximum likelihood estimator calculates second maximum likelihood values corresponding to the NW angles in a second direction by performing a maximum likelihood estimation process on the second direction using signals received by a second virtual linear array and extracts second candidate angles of arrival of incoming waves in the second direction. A horizontal/vertical maximum likelihood estimator estimates, using the first and second candidate angles of arrival, angles of arrival of the NW incoming waves in a two-dimensional plane extending in the first and second directions.

Abstract: In a position estimation processing unit, by using the reflected wave signal of an array composed of receiving antennas arranged in a first direction among a plurality of receiving antennas, a maximum likelihood value extraction unit extracts the angle of arrival of a reflected wave signal in a first direction. An angle spread detection unit detects the angle spread in the first direction around the angle of arrival by using the reflected wave signal of the array. A target height estimation unit estimates the position of the target in the first direction by using the angle of arrival and the angle spread.
