Light Detection and Ranging (LIDAR) | |
|
The LIDAR system also nicely complements the MST
Radar. The Lidar system installed at NMRF can be operated in Mie as
well as Rayleigh modes. This Lidar system can be used to obtain aerosol
distribution upto about 20 km and temperature / density in the heightrange
of 30 - 80 km . The Lidar transmitter employs a PL8020 model Nd :
Yag pulsed Laser which is a solid state class of Laser source. This
system uses 532 nm with a maximum energy of 500 mJ per pulse .

The
reciever sub-system employs two independant recievers to recieve Rayleigh
and Mie backscattered signals.The Rayleigh scattering gives rise to
backscatter signal from air molecules where as Mie scattering arise
due to backscatter from aerosols and cloud particles
