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.

Keywords: autocorrelation receiver, synthetic aperture radar, radiotechnical monitoring, analog-to-digital converter, programmable logic integrated circuit.
