2.5 Reduction of noise on images
Images of echo sounders display noise due to various causes.
The causes of noise are:
1. Interference caused by reception of signals transmitted by other echo sounders
2. Blur due to micro animate beings such as plankton
3. Noise caused by electric signal synchronized with transceiver
CVS-702D is equipped with functions to weaken the effect by each cause.
2.5.1 To reject interference
Interference is generated by the reception of signals transmitted by other echo sounders.
CVS-702D can reject interference by setting [IR (Interference Rejection)] function.
