| 摘要 |
The invention relates to a method for the passive determination of target data by means of a directionally-selective reception of sound waves, wherein a first converter arrangement uses estimated bearing angles, which are determined from estimated positions of a target, and measured bearing angles, to minimize bearing angle differences between measured and estimated bearing angles. In order to enable a suitable determination of the target data, with respect to time considerations for tactical requirements, without requiring an individual maneuver and frequency evaluation of the received sound waves, claimed bearing angle measurements of a second converter arrangement, located at a distance from the first converter arrangement, are utilized for the estimation of the target data when a parallax value determined between the bearing angle measurement of both converter arrangements is greater than a prespecifiable parallax threshold value, and the distance estimated during the target data estimation is smaller than a comparison distance determined from the parallax threshold value.
