Advanced HF Radar Systems Engineering Plan

Define performance objectives for multi-static operation, system requirements for large-scale deployment architecture, and interfaces for second shore station. Tasks include purchase, installation, association analysis, implementation planning, and vessel detection design. Bistatic interface development and refinement of multistatic detection technologies are essential. Real-time transition studies aim to automate detection file production and enhance data transfer efficiency.
