DIRECTION-FINDING METHOD AND INSTALLATION FOR DETECTION AND TRACKING OF SUCCESSIVE BEARING ANGLES
A direction-finding method and apparatus for detection and tracking of successive bearing angles of sound-emitting targets, wherein intensity plots of successive clock cycles in a waterfall plot show bearing traces of successive bearing angles, and preferred bearing traces are marked by a tracker.

| description | A direction-finding method and apparatus for detection and tracking of successive bearing angles of sound-emitting targets, wherein intensity plots of successive clock cycles in a waterfall plot show bearing traces of successive bearing angles, and preferred bearing traces are marked by a tracker. In order to automate the setting and deletion of trackers, starting from trace state vectors, which are determined at the time t=k−1, are each associated with one bearing trace and each have a bearing angle as well as its time derivative, which is referred to as the bearing rate, and possibly an intensity and its time derivative, which is referred to as the intensity rate, and trace errors associated with the trace state vectors for the time t=k, predicted state vectors are predicted together with predicted estimation errors. Bearing traces are displayed as a function of a trace quality |
