Abstract:

The operation of all depth sounders will be improved when the receiver bandwidth is such that the peak signal to RMS noise ratio is maximum. This occurs when the receiver bandwidth is adjusted to approximate a matched filter. For the Raytheon DE723M after the bandwidth is properly set, a proper time-variable gain and automatic gain control should be incorporated into the receiver. If the system performance after these modifications is still less than desired, modification to the logic should be implemented. All modifications recommended should not require a significant amount of space and can be incorporated into the present chassis.
