Figure 5From: Translational motion compensation for ISAR imaging under low SNR by minimum entropyComparison of approaches under different SNRs. (a) Coarse motion estimation under SNR = −7 dB. (b) Coarse motion estimation under SNR = −10 dB. (c) RD images under SNR = −7 dB. (d) RD Images under SNR = −10 dB.Back to article page
