Evseev I. Space-time signal processing optimization in bistatic synthetic aperture radar

The thesis is devoted to increasing effectiveness of the surface imaging by using bistatic SAR as elements of the multiposition remote sensing system and by optimisation of the space-time processing; SAR coherent processing signals channels structure creation with transmitter and receiver position spaced and move at own independent trajectories are approved; unambiguity measurements peculiarities in bistatic SAR are considered; optimal complex scattering coefficient and effective radar cross-section estimation algorithm are derived; research of continuous pseudonoise signals in bistatic SAR usage peculiarities is carried out; the possibility of bistatic SAR resolution increasing taking into account non-stationary and stochastic character of electromagnetic field reflected from the surface is shown. Results of the theoretical investigation allow to increase quality of the radar image formation and electrophysical parameters estimation and assist in solution of the different application of the aerospaceremote sensing systems and may be used in different aerospace organizations.
