摘要： A system is disclosed that enables the use of an incomplete SONAR array matrix in a correlation SONAR system. An improvement is achieved through the generation of a correlation-array model matrix of hydrophone correlations, based on an independent estimate of the ship's velocity, such as from an inertial navigator. Meanwhile, estimates of the missing values are generated based on one or more values from the model matrix, an interpolation of values from the SONAR array matrix itself, or some combination thereof. Regardless of how the missing values are generated, the model matrix provides a basis for comparison with the SONAR array matrix, which is populated with the estimated values, wherein subsequent comparisons are made between successive iterations of the model matrix and the SONAR array matrix. By applying the disclosed technique, a correlation SONAR system with incomplete data is able to continue working, and in the presence of a greater number of hydrophone failures than before.

摘要： A correlation SONAR that provides improved velocity estimates due to a reduction in random and bias errors is disclosed. Rather than basing the velocity estimate on a single set of primary receiver pairs, one or more additional velocity estimates are generated based on one or more available receiver pair sets having the same velocity vectors as the primary receiver pairs set. Additional velocity estimates also provide a reliability and accuracy improvement by enabling identification and subsequent elimination of erroneous velocity estimates.

摘要： A sonar system comprises a transmitter adapted to provide pulse sequences, wherein each of the pulse sequences includes pulses that reflect off an object, a receiver adapted to receive the reflected pulses, and a processor. The processor is configured to transmit a first pulse sequence via the transmitter to obtain a first distance to the object in a first distance range and to transmit a second pulse sequence via the transmitter to obtain a second distance to the object in a second distance range. The processor is configured to transmit the second pulse sequence in response to being unable to obtain the first distance to the object in the first distance range.

摘要： A temporal correlation SONAR calculates the velocity and position of a water navigable craft. A first pulse and a second set of pulses are transmitted towards an ocean bottom. A tetrad of hydrophones on the craft receives echoes of the pulses. A correlation between the first pulse received on one hydrophone with the second pulses received on another hydrophone produces correlation points, for which a correlogram is generated. The distance between the hydrophones is divided by twice the time value at the peak of the correlation to calculate the velocity of the vessel. Another correlation is generated for hydrophones pairs that are positioned diagonally from one another, and maximum correlation values, along with hydrophone angles, are used to calculate athwart-ship velocity.

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： 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.
摘要翻译：公开了一种在水听器阵列中检测故障水听器通道的改进的系统。所公开的技术在两个或更多个水听器的组上操作成一对水听器或者将其概括为一组; 这与一次只在一个水听器上操作相反。结果，该技术能够使用来自多个水听器的相关数据，以便检测故障。该技术还对与正在进行的SONAR解决方案处理相关联的接收回波信号信号进行操作。使用相对确定性的回波信号信息进一步提高了性能。通过使用由接收到的回波信号信息组成的相关乘积，所公开的技术能够利用已经依赖于水听器阵列的SONAR解决方案处理，例如空间或时间相关SONAR，从而减少所引起的附加处理。一旦识别出失效的水听器通道，则将其从正在进行的SONAR解决方案处理中排除。
