Title:
TARGET RECOGNITION DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/190719
Kind Code:
A1
Abstract:
This position information acquisition unit, which acquires position information on the basis of a target detection signal from a target sensor (2), is provided with a first acquisition unit (111) which uses a first threshold value to acquire first observation information as position information, and a second acquisition unit (112) which uses a second threshold value different from the first threshold value to acquire second observation information as position information. A target tracking unit (13) is provided with a first tracking processing unit (131) which performs tracking processing on the basis of the first observation information, and a second tracking processing unit (132) which performs tracking processing on the basis of the second observation information, wherein one of the first tracking processing unit and the second tracking processing unit has higher clutter resistance characteristics than the other. A state specifying unit (15) specifies the state of a target on the basis of the results of the tracking processing by the target tracking unit.
