Paper Abstract

This paper is focus on analyzing the telescopes used in atmosphere, which studies the effect of optical aberration of telescopes to the laser radar. The method of numerical simulation is used to calculate and analyze the characters of backward wave when laser beam propagates through atmosphere and reflects back. Then make use of optical transfer function including quartic phase aberrations to get the beam quality denoting the laser beam pass through the telescopes system with aberration. It takes advantage of angle-of-arrival fluctuations, radius of power in bucket, and scintillation to study the effect of wavefront errors to laser radar. Furthermore, comparing the scintillation of backward wave by diverse intensity of atmospheric turbulence, it discusses the effect of optical aberration to the accuracy of radar. By synthetically numerical analyses, this paper concludes the quantificational effect of different aberration of telescopes to the signal of radar. The conclusion of this paper can be used to direct the design and manufacture of telescopes of optical radar.
