摘要： The invention relates to passive target data determination, wherein target noises are received with a sonar receiver device onboard a carrier vehicle and the bearing angle to a target is measured. An estimated bearing angle is detected on the basis of a target position that has been estimated with a speed-dependent path term and path component and speed component errors. A bearing angle difference relative to the measured bearing angle is then formed and iteratively minimized. A frequency analysis of target noise is carried out and reception frequency is measured in order to determine target data, said determination being adapted in time to tactical requirements, without inputting measured values of other sensors onboard and without performing any individual maneuver. A Doppler shift of an estimated transmitter frequency having a frequency error is determined on the basis of the estimated target positions and their changes in time in the direction of bearing and a Doppler frequency is estimated. The frequency difference between the measured reception frequency and the Doppler frequency is iteratively minimized along with the bearing angle difference. The position estimated when the minimum has been reached provides the target data.

摘要： The invention relates to a method for generating target-marking directional tracks for a plurality of sound-emitting targets in a sea area directed by a plurality of sensors, each sensor providing a sensor track made of sequential bearings for each found and tracked target. In order to reduce the plurality of directional tracks to only as many target-marking directional tracks as targets found by the totality of sensors, and in order to correctly assign track segments between which gaps in time occur, sensor tracks of a plurality of sensors that are derived from a common target are consolidated into contact tracks - starting from the sensor tracks of the most accurate sensor - to form a track-to-track fusion, and contact tracks that are offset in time are checked for the probability of them belonging together. Contacts tracks that are offset in time and have a high probability of belonging together are associated with each other and designated as uninterrupted target tracks.

摘要： The invention relates to a method for determining and representing possible target parameters, in particular of a target distance R, a target course C and/or a target speed V of a target. For this purpose, a plurality of different target tracks Z(i, j) having associated quality information are determined from the possible solutions during each processing cycle of an optimization method that is applied. Future target positions (25), which together with the quality information form a future expectation area (42), are determined for said target tracks Z(i, j). In addition, a distance solution space (34) and a vector indicating the best solution Z
best is determined from the possible solutions. The future expectation area (42), the distance solution space (34) and/or the best solution Z
best can then be represented in a single solution space in the form of a position representation on a display device (27).-

摘要： The invention relates to a method for determining target parameters by the direction-selective reception of sound waves which are emitted or transmitted by a target, with an array of waterborne-sound sensors (20) of a sonar receiving system. Bearing angle differences are determined from estimated bearing angles B
est , which are determined from estimated positions of an assumed target track Z(i, j) of the target, and from bearing angles B
est measured by the array (20). At least one support value is determined from a set of possible support values, said support value being used to determine a respective evaluation quantity Q(i, j) for one or more target tracks Z(i, j), wherein the evaluation quantity Q (i, j) is determined from the bearing angle differences associated with the respective target track and at least one support value. A best target track Z
best having associated target parameters is determined on the basis of said evaluation quantities Q(i, j), wherein said associated target parameters are output as the target parameters to be determined. The invention further relates to a device for carrying out the method according to the invention.-

摘要： The invention relates to a method and an apparatus for passive determination of target parameters by directionally selective reception of sound waves which are emitted or transmitted from a target, to be precise by means of an arrangement (24) of underwater sound sensors of a sonar receiving installation from estimated bearing angles, which are determined from estimated positions of the target, and bearing angles which are measured at the measurement point by the arrangement (24), wherein a bearing angle difference between measured and estimated bearing angles is iteratively minimized and, when the minimum is reached, the target parameters are used for an optimized solution for outputting target range, target position, target course, target range and/or target velocity and they are updated during each processing cycle in a series of successive processing cycles. In order to estimate the reliability of this optimized solution, during each processing cycle a multiplicity of different target tracks Z(i, j) are calculated from possible solutions for the target parameters to be determined, specifically an assumed target course C
est , an assumed target range R
est and/or an assumed target velocity V
est . Associated bearing angles B
est are assumed for each of these possible solutions, and the assumed bearing angles B
est are used to calculate a quality measure Q, Qinv along each of the assumed target tracks Z(i, j). In order to determine the reliability of the optimized solution, a reliability level is determined from the distribution of the quality measure Q, Qinv, as a function of at least one of the target parameters. The entire calculated solution scope for the various target parameters corresponding to the associated quality measure Q, Qinv is advantageously visualized in various diagrams.-

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.

摘要： The invention relates to a test method for a process used for passively obtaining target data of a moving target that radiates wave energy, particularly sound. According to said method, bearing angles are measured as real target data by taking the bearing of the target by means of an on-board bearing system at successive path positions of a vehicle, particularly a watercraft that determines the path positions thereof with the aid of a compound navigation system, and the distance, speed, course, and/or position of the target are determined therefrom as additional real target data. In order to be able to quickly verify the serviceability of said TMA method on line in a sea acceptance test, the positions of the target and the vehicle are measured using a GPS at the moments in time the bearings of the target are taken. The bearing angle and the distances of the target are calculated from the respectively associated positions of the vehicle and the target and are allocated to the path positions that are measured using compound navigation. A reference target path is estimated therefrom as well as from the associated pairs of values of the bearing angle and the distance of the target by means of estimation filters, and reference target data is derived therefrom so as to be directly compared to the real target data.
