High-Processing Method of Spectral Analysis Wide-Signals

A high-performance spectral analysis method for broadband signals is presented, which is based on the theory of digital signal processing. According to the proposed method, the partition of a broadband signal selection array is performed on a number of sub sequences. The formed subsequences are processed in accordance with the Fourier Fast Transform (FFT) algorithm. In the framework of the proposed method, expressions were obtained for calculating the main parameters of FFT structure.The analysis of the efficiency of the proposed method has proved that the productivity of the digital spectral analysis of broadband signals increases in 1,2 ÷ 4,7 times, depending on the length of the processed subsequence and the volume of the analyzed sample of the signal.
