TARGET DETECTION APPARATUS AND TARGET DETECTION METHOD
First Claim
1. A target detection apparatus applicable to a radar system comprising a plurality of receiver devices each of which receives, by a receiving antenna, an echo from a target based on a radio wave transmitted from a transmitting antenna of a transmitter device, the apparatus comprising:
- a plurality of tracking processors configured to obtain a plurality of target positions by individually tracking a plurality of video data output from the plurality of receiver devices, respectively; and
a correlation processor configured to extract a combination of echo signals from the same target based on a correlation relationship between a position of the transmitting antenna, positions of the receiving antennas of the plurality of receiver devices, and the plurality of target positions.

Abstract
According to an embodiment, a target detection apparatus is applicable to a radar system. The radar system includes receivers each receives, by a receiving antenna, an echo from a target based on a radio wave transmitted from a transmitting antenna of a transmitter. The target detection apparatus includes tracking processors and a correlation processor. The tracking processors obtain target positions by individually tracking video data output from the receivers, respectively. The correlation processor extracts a combination of echo signals from the same target based on a correlation relationship between a position of the transmitting antenna, positions of the receiving antennas of receivers, and target positions.
