This paper describes the development of the SeaSonde High Frequency Radar system into a dual-use application for the mapping of ocean surface currents and detection of ships at sea. This development entailed the creation of a new radar waveform that would permit this dual-use as well as a detection algorithm to identify the ships in the radar spectra. The detection algorithm utilizes two method...

The termination of activation signals is a critical step in the control of the immune response; perturbation of inhibitory feedback pathways results in profound immune defects culminating in autoimmunity and overwhelming inflammation. FcgammaRIIB receptor is a well described inhibitory receptor. The ligation of B-cell receptor (BCR) and FcgammaRIIB leads to the inhibition of B-cell activation. ...

Inshore ship detection is an important task in several fields, for example, maritime transportation, supervision, and port management. However, due to the diversified categories locations of different ships interference complex surroundings, capturing discriminative characteristics multi-scale inshore accurate still challenging. Here, anchor-guided attention refinement network (AARN) proposed a...

We give an overview of some R&D projects in SAR imagery at Lockheed Martin Canada. These projects are motivated by airborne surveillance applications such as the landmass and coastal surveillance missions of the Canadian CP-140 (Aurora) aircraft. The activities reviewed here are 1) R&D supports to CP-140 Spotlight SAR upgrade, 2) fast multiresolution prescreening filter for CFAR detection, 3) c...
