The length of battle array is about the one third of captain to half, and sound aperture is big, and spatial gain is high, is easy to use low frequency operation.?
Ship it is left and right can each one array of cloth, space duality is not present, distorts and loses without formation, also using hull vertical space,
Vertical gain is obtained, reduces the influence of multi-path jamming, operating distance is generally up to tens of nautical miles.
The conformal array sonar being on active service at present is piezoelectric type hydrophone, yet there are no the phase of all -fiber hydrophone conformal array sonar
Close report.Fibre optic hydrophone is high with sound pressure sensitivity compared to piezoelectric type hydrophone, detection range is remote, low frequency response is high, dynamic
The advantages such as range is big, strong antijamming capability, single hydrophone are small in size, while passing through time division multiplexing, space division multiplexing, wavelength-division multiplex
Equal multiplex modes can extensive Cheng Zhen, improve spatial gain.Thin footpath, light-weight array is easily made in all -fiber battle array, is easy to latent
It installs and uses on ship, in conjunction with the effective noise reduction technology of mounting platform, low frequency even very low frequency section can be effectively treated
Acoustical signal.
Utility model content
