, it does not make the difference between the two principal diagonals. The better directional selectivity of the proposed implementation of HWT versus the 2D DWT can be easily observed, comparing the corresponding detail sub-images in figure 10. For the diagonal detail sub-images, for example, ...

Traditional transducers put you on hold, wasting valuable time “charging up” before each sonar pulse. Humminbird CHIRP transducers are engineered to minimize charge time, firing off more pulses in a given period of time. More pulses mean more information and improved target separation. ...
other platforms to detect the active sonar at a far greater range. That is due to the power of the signal: for instance, an actve radar emits a signal of 20 W and is capable of detecting an echo of 4 W (these values are hypothetical). A target is at 20 km. If that target ...

A subtractor (16,18) forms the differences of the respective coordinates. A third subtractor (17) forms the difference between the differences and is connected to a comparator (19).WORCH, JUERGEN, DIPL.-ING. FH, ULM, DE
Sonar technology, particularly hull-mounted or towed arrays, allows submarines to navigate in deep waters where radar is ineffective. Sonar helps detect nearby objects or terrain features, enabling safe travel through otherwise uncharted areas, improving navigational accuracy and safety. ...
