Abstract.
The article presents two variants of the functional
diagram of the digital autocorrelation receiver (DACR) SAR signal processing
and requirements for its functional devices considering relative displacement
of the spacecraft engaged with SAR and aerial vehicle with radiotechnical
monitoring equipment. The influence of relative displacement of the
spacecraft engaged with SAR and aerial vehicle with radiotechnical monitoring
equipment at LFM signal processing in DACR is
investigated.
