Abstract
Reflected sonar signals arising from one or more possible unknown objects are distinguished according to a first criterion, and possible shapes each having a defined unique associated point are assigned each of the possible unknown objects. Then the three dimensional points are tracked by the sonar system.
Claims15
A method, comprising:
- directing a first one or a first series of pulsed sonar beams into a volume of fluid, wherein the one or a first series of pulsed sonar beams is produced by a pulsed sonar beam generator in communication with the volume of fluid;
- receiving sonar signals from the volume of fluid, wherein the received sonar signals are received by a sonar signal receiver;
- analyzing the received sonar signals for each of the first one or each of the first series of received pulsed energy signals, wherein the analysis is performed with a first analysis method;
- distinguishing sonar signals arising from reflections of sonar beams from one or more possible unknown objects, wherein the sonar signals are distinguished according to a first criterion;
- assigning first possible shapes to the one or more possible unknown objects according to a second criterion, wherein each of the first possible shapes have a defined unique associated point;
- calculating three dimensional coordinates of the defined unique associated points;
- and
- changing at least one of the characteristics of a pulsed energy beam producer or the energy receiver wherein the characteristics are changed in response to the analysis according to a third criterion, wherein the characteristics are at least one of a range, gain, frequency, and field of view.
