Shutko V. The Spline-Fourier Methods and Facilities for Increase of Functioning Efficiency of the Automated Management Systems

The new spectral method for doppler radio-locating signals detection is proposed. A priori unknown deflections of real signals from ideal harmonic model bring to considerable falling of detecting characteristics. The proposed method is remarkable for its stability to these deflections. Using of this method show the sizeable effectiveness for processing real signals recording. Middle gain in signal-to-noise ratio is 60% for power. The device for realization of the algorithm for calculating spline-Fourier transformation is based on programmable logical integral circuits. Using of this method allow to attain goal characteristics of radio-locating station with the less power of transmitter. This is decrease radiation treatment of attendants. Mathematical works and original algorithms of the unstationary quasicoherent signals processing are used in the apparatus of the modernized side automated information-computer system of multifunction airplanes An-148, An-124 according to demands of ICAO.
