- Abstract
- We consider the vector S-parametric analysis of the phase-dynamic radio images through the formation and numerical analysis of the S21-component of the scattering matrix of quasi-stationary and dynamic signatures of radio-visual objects. The key advantages of aperture capture of radio signal images using the method of frequency-synthesized power spectral density function of the scattered wave radio profile are determined. On the basis of the vector circuit analyzer microwave range and broadband antennas such as "Vivaldi" built experimental-laboratory installation of signal capture of scale-time radio images in the spectral region of 0.03-6.0 GHz. The dependences of the influence of the angular characteristics of the object on the spectral-temporal structure of the formation of phase-dynamic radio-images are experimentally established. The method of cepstral transformation of S-parametric characteristics with convolution of basic signatures in the radiogenome of the irradiated object is proposed as a scale-temporal post-processing of radio-images. A series of cepstral convolutions of the phasodynamic radio images, establishing a functional connection between the object's signature change in time and its radiogenome, has been obtained. It was found that the reproducibility of the proposed method at signal/noise ratio of 12 dB is not less than 0.9.
