Abstract : The report gives a detailed description of the different steps in the processing of 'drift' data taken with the Complex Amplitude Multifrequency Scanner (CAMS). The raw data together with preface information are digitally recorded in a format suitable for a 'digicoder' printout. They are spectrum analyzed in two steps: Fourier spectra and combined power, phase and coherency spectra. Output is provided either as computer plot or as tape for 'digicoder' printout. The last step is a DAASM (Doppler and Arrival Angle Measurement) display. As illustration for all these steps in the data processing an E sub S event was chosen which appeared one hour after chemical releases from rockets. Only minor attention has been given to the interpretation of the processed data. (Author)
