The article proposes a method for calculating the sensitivity adjustment of the laser spot recorder during planning and during conducting ground and flight experiments. The method is based on the calculation of the radiation flux [1, 2] incident on the detectors of the registration system, taking into account the range and angles of sight of the target, the characteristics of the emitter and weather conditions. It is proposed to adjust the sensitivity threshold of the laser spot recorder in two ways: a) static, before conducting a flight experiment: the sensitivity of the detectors is set based on a given range of illumination range, in which it is necessary to ensure the required accuracy of registering the spot position; b) dynamic, during the flight experiment: automatic adjustment of sensitivity taking into account changes in the spatial position of the air-based illuminator relative to the target during the flight. Each of the methods allows to reduce the time and material costs of preparing experiments, as well as to increase the reliability of estimates of the position of the energy center of the spot on the target.
