In the approximation of the Debye diffraction integral, we calculate the amplitude—phase distribution in the main lobe of the probing radiation. The results of the calculation are used for power analysis of the optical information signal of a laser

The power of the information- carrier optical signal of a laser Doppler airflow velocimeter is estimated in the simple example of an aberrationless spherical transceiver antenna and under the conditions of the model of a “pure atmosphere”.
