In order to realize non-line-of-sight (NLOS) laser scattering communication in atmosphere, the NLOS communication link model was founded according to Mie scattering theory and 1.06m laser scattering communication in atmosphere was studied. The relationship of laser receiving power, laser transmitting power, laser beam divergence angle, receiver field of view, detector sensitivity, emission inclination angle, receiver inclination angle, atmosphere attenuation and communication distance were analyzed. After establishing the experimental system, an experiment of 1km scattering communication was taken on and laser scattering signal was gotten. The experimental result shows that atmosphere scattering communication at long distance can be realized by choosing 1.06m laser for signal communication under a certain weather condition.
