| 成果简介 | NOVELTY - Invention relates to simulation of radar characteristics of objects for broadband signals and can be used to construct two-dimensional inverse synthesized radar images (RI) by calculation methods for solving electrodynamic problems of wave scattering. In the disclosed method, a digital facet-edge model of an object is developed, from the required resolution and dimensions of the obtained radar image, the frequency band of the probing radar signal is set, values of the frequency increment of the probing radar signal and the object observation angle, the spatial frequency measurement boundaries are calculated, the observation angle change plane and the object rotation axis location are set, values of amplitude and phase of the signal reflected from the object are calculated for each element of the two-dimensional matrix of complex envelopes in coordinates of spatial frequencies and subsequent transformation of the matrix using the inverse two-dimensional Fourier transform into a two-dimensional matrix of synthesized complex responses, all elements of which represent a two-dimensional radar image of the object. USE - Radar. ADVANTAGE - Obtaining a two-dimensional radar image of an object, which is synthesized from the results of calculating the amplitude and phase of a radar signal reflected from it in a wide range of probing frequencies and location angles. 1 cl, 4 dwg, 1 tbl |
