At the Institute of atmospheric optics of Russian Academy of Science (IAO SO RAS), the automatic express control equipment for atmospheric pollution and remote detection of aerosol and gas emissions from industrial enterprises is created over a remote method detecting radioactive anomalies on secondary displays of radioactivity. Matching several original scientific and technical decisions in one complete equipment essentially expanded opportunities of registration of emission and absorption spectra in several spectral ranges. The automated system of data processing includes some program modules, each of which is intended for the decision of specific tasks, and needed special techniques of testing. In the given paper original techniques of testing of a program complex and subprograms processing experimental data and calculations are presented. So, testing of the microwave Spectroradiometer module is based on graduation of a frequency scale, on the basis of which frequency of the signal is determined. The technique of testing and calibration of the measuring data from TV-system represents the procedure similar to television tests. The technique of testing forecast optical noise in the atmosphere is based on use of algorithms of comparison with standard optical models. In a basis of testing technique of the program module of optical correlation spectrophotometer, the graduation of a scale of voltage from two channels of analog-digital converter, which is carried out proceeding from values of the signal impressed from the external photoelectronic multiplier. Results of testing, which have shown serviceability of separate modules and a complex of programs as a whole and reliability of received results, are shown.
