Beschreibung
Zusammenfassung:	The invention provides a high-speed platform real-time SAR imaging method, device and system and a storage medium. The high-speed platform real-time SAR imaging method comprises the steps of S1, performing distance dimension processing on echo data; and S2, a motion error coarse compensation stage. And S3, performing echo Doppler center frequency estimation on the echo data after coarse compensation. And S4, performing echo Doppler frequency modulation rate estimation on the echo data after coarse compensation. And S5, performing an imaging processing stage according to the echo data after coarse compensation, the Doppler center frequency and the estimated value of the Doppler frequency modulation rate: performing dechirp on the azimuth dimension of the echo signal matrix s2 (tau, eta) after coarse compensation of the motion error according to the estimated value fdc (m) of the Doppler center frequency and the estimated value fdr (m) of the Doppler frequency modulation rate, the method comprises the following
