Sonar depth tracking system |
| abstract |
A system, selectively responsive to the first, peak, or last portion of a radiant energy signal for displaying a gate which brackets the radiant energy signal and also provides means for inhibiting the generation of such signal during a preset time interval preceding the gate. Means are also provided for automatically widening the gate and repositioning the gate to insure tracking of the radiant energy signal. The system is particularly adapted for monitoring a sonar depth recording to provide audible and visual alarms when the sonar data becomes excessively noisy and during sudden changes in the water depth. |
