Sonarchaff
Net is an alternative variant, again delivered via 130 mm munitions, but
here the Sonarbells are attached to nets, that not only create highly
confusing sonar returns, but also act as a physical barrier, impeding
the torpedo and fouling propulsion systems. The third line of defence is SonarMimic, this uses Sonabells with very specific return strengths on a rapidly deployed towed array, that exactly mimics the sonar and Doppler signature of the towing vessel. Following a rapidly executed turn, the torpedo is presented with a strong, exact replica of its target, upon which the torpedo, in terminal mode expends itself. These systems are an elegantly engineered, simple solution, designed to be operated widely across fleets. |

The
SonarBell works through the constructive interference of sound waves when
they meet after transiting the shell and core. It is totally passive and
omnidirectional. The maximum target strength varies from -5 dB to -30
dB across the frequence range of 4 kHz to 1.8mhz. Specific frequencies and target strengths are achieved by changing the thickness of the shell and other properties. The range depends on SonarBell size and frequency of the sonar. |
