Table 1 Entropy evaluation
From: Translational motion compensation for ISAR imaging under low SNR by minimum entropy
5 dB | 0 dB | −5 dB | −10 dB | |
|---|---|---|---|---|
Ideal | 7.170 | 8.169 | 8.813 | 9.155 |
MERA + MEPA | 7.253 | 8.211 | 8.861 | 9.201 |
Proposed method | 7.181 | 8.173 | 8.812 | 9.183 |
