In the given work the methods of digital data processing are considered with the purpose of aircraft model surface pressure distribution field obtained with the PSP method accuracy increase. The problem consists in correction of luminescent distribution field in places of aircraft elements interface. The methods of elimination of illumination from various aircraft surfaces are considered in view of real geometry. For the first time given problem was delivered in [14]. For modelling of self-illumination the mixed model of diffuse-mirror reflection with trace of beams was chosen. It was shown that by selection of the reflecting sublayer characteristics it is possible to reduce mirror component practically to negligibly small values. The check was carried out by means of account both mixed model, and complete diffuse model.
