Abstract
The need for air-to-ground missiles with day/night, adverse weather and pinpoint accuracy Autonomous Target Acquisition (ATA) seekers is essential for today's modern warfare scenarios. Passive millimeter wave (PMMW) sensors have the ability to see through clouds; in fact they tend to show metallic objects in high contrast regardless of weather conditions. However, their resolution is very low when compared with other ATA sensor such as laser radar (LADAR). We present an ATA algorithm suite that combines the superior target detection potential of PMMW with the high-quality segmentation and recognition abilities of LADAR. Preliminary detection and segmentation results are presented for a set of image-pairs of military vehicles that were collected for this project using an 89 Ghz, 18 inch aperture PMMW sensor from TRW and a 1.06 (mu) high-resolution LADAR.
