Table 2 Whole performance comparisons among the three algorithms in a complicated environment
From: SAR image target detection in complex environments based on improved visual attention algorithm
| Â | Number of all targets | Number of detected targets | False alarms | Number of undetected targets | Size of FOA (number of pixels) |
|---|---|---|---|---|---|
Classic algorithm | 13 | 12 | 6 | 7 | 2,000 to 9,000 (large) |
CFAR | 13 | 27 | 14 | 0 | - |
The proposed algorithm | 13 | 13 | 0 | 0 | 1,000 to 1,500 (small) |
