This product contains 29,000+ target, false alarm, and pwf (polarization whitening filter) image chip files to support ATR algorithm evaluation. The chips consist of test and training sets of the M48 tank and M55 howitzer. The following parameters apply to data in this kit:
| ADTS Missions | Target (M77 & M83) False Alarm (M78, M90, & M140) |
|---|---|
| Training Set | M48 tank at 345 aspects M55 howitzer at 325 aspects |
| Test Set | M48 tank at 68 aspects M55 howitzer at 68 aspects |
| Clutter Sites | Stockbridge, NY, Rural (56km2) Ayer, MA, Urban (18km2) |
| Depression/Squint | 22.5 degrees/40.0 degrees |
| Polarizations | HH (pol0), HV (pol1), & VV (pol3) |
| Image Size | 128 x 128 |
| PWF Data Chips | 32-bit float Polarization Whitening Filters |
| Data Type(s) |
|
There are NO headers on the chip data. All of the chip data is stored in Sun binary big-endian format. If you intend to use the data on a machine using a different byte-order, you will have to byteswap the data.
