摘要： A system is disclosed that provides an improvement in detecting a faulty hydrophone channel in a hydrophone array. The disclosed technique operates on pairs of hydrophones or, to generalize, on groups of two or more hydrophones; this is in contrast with operating on only one hydrophone at a time. As a result, the technique is able to use correlation data from the multiple hydrophones, in order to detect a fault. The technique also operates on received echo signal information that is associated with ongoing SONAR solution processing. The use of the relatively deterministic, echo signal information further enhances the performance. By using correlation products made up of the received echo signal information, the disclosed technique is able to leverage the SONAR solution processing that already relies upon the hydrophone array, such as spatial or temporal correlation SONAR, thereby reducing the additional processing incurred. Once a failed hydrophone channel has been identified, it is then excluded from the ongoing SONAR solution processing.

摘要： A system is disclosed that provides a sonar system featuring combined spatial and temporal correlation array processing. The disclosed system merges spatial-based velocity errors with temporal-based velocity errors by using a combining algorithm that is based on the optimization criteria that the output after combining has no bias error and has a minimized mean square error. With these criteria, the combining algorithm takes the form of a weighted summation of the spatial data stream and temporal data stream inputs with the weights being a function of the relative velocity errors. In combining spatial and temporal processing in this manner, the disclosed system provides improved velocity measurements for a wider range of ship's speeds. In particular, the system achieves performance levels of a spatial correlation sonar for low ship's speeds for which a temporal correlation sonar solution might not be available. The system also achieves performance levels of a temporal correlation sonar for high ship's speeds for which a spatial correlation sonar solution might not be available.
摘要翻译：公开了一种提供具有组合空间和时间相关阵列处理的声纳系统的系统。所公开的系统通过使用基于优化标准的组合算法将基于空间的速度误差与基于时间的速度误差相结合，组合后的输出没有偏差误差并具有最小均方误差。利用这些标准，组合算法采用空间数据流和时间数据流输入的加权求和的形式，权重是相对速度误差的函数。在以这种方式组合空间和时间处理的情况下，所公开的系统为更广泛的船舶速度提供改进的速度测量。特别地，该系统实现了对于时间相关声纳解决方案可能不可用的低船速的空间相关声纳的性能水平。该系统还实现了对于船舶的高速度的时间相关声纳的性能水平，其中空间相关声纳解决方案可能不可用。

摘要： A method of estimating velocity with a correlation SONAR that provides improved velocity estimate due to a reduction in random and bias errors is disclosed. The method generates a velocity estimate based on a weighted average of pulse-pairs that includes processing of those pulse-pairs based on an optimal correlation time as well as pulse-pairs based on sub-optimal correlation times.
