Abstract
The effects of transmitted laser beam steering due to atmospheric turbulence can be corrected by the use of a tracking sensor that views the receiver through the same turbulence. For an airborne transmitting system, the power spectrum of the steering can have high frequency components. The tradeoff between the aperture size for the tracking sensor, the laser transmitting aperture size, and the bandwidth of the closed loop tracking system are shown.Keywords
