China’s scientists are
developing a super-sensitive radar that can detect the wing-flapping of
mosquitoes up to 1.5 kilometers away.
At the
laboratory of Beijing Institute of Technology the blueprint of device is being
tested.Researcher said that “recognizing and tracking mosquito-sized targets is
no longer science fiction”.Researcher said that they will use this technology
for saving lives.
According to
the World Health Organisation mosquitoes are the reason for one million deaths
each year and mosquitoes have claimed more human lives than all wars combined.
After decades of
development of technology, modern military radars are now able to pick up the
echoes of small objects at an impressive distance. The US Missile Defence
Agency’s sea-based X-band radar can detect a
baseball-sized object from about 4,000-5000 km away.
According to
scientists working on the project,the super-sensitive radar will work by
emitting rapid pulses of electromagnetic waves that travel at many frequencies.
Scientists in other
countries have used civilian radar networks to track the group movement of
birds or larger insects such as locusts and moths, but this is believed to be
the first attempt to use radars to monitor mosquitoes.One of the
researcher said that “Mosquito wings
ofcourse are a lot different from the metal wings of a military jet, and so are
their structures, shapes and movements. The mosquito radar is going to need a
completely new set of algorithms”.
Scientists
working on the project said that “The biggest challenge will come from the
environment”,since the radio waves from a mosquito were extremely weak and
could easily be conquer by background noise.
Good work keep posting some more articles
