In a prior paper, we described a new imaging architecture that addresses the need for wide field-of-view imaging combined with the resolution required to identify targets at long range. Over the last two years substantive improvements have been made

This work documents the performance of a recently proposed generalized likelihood ratio test (GLRT) algorithm in detecting thermal point-source targets against a sky background. A calibrated source is placed above the horizon at various ranges and th

We introduce a detection and tracking algorithm for panoramic imaging systems intended for operations in high-clutter environments. The algorithm combines correlation- and model-based tracking in a manner that is robust to occluding objects but witho
