Considerations in radar system engineering

The nature of systems is discussed, using a framework of estimation, decision and action spaces to address overall behavior. The process of relating operational requirements to the specifications that govern actual development ("functional allocation", key to system engineering) and some tools useful in that process are discussed. The inseparability of engineering and management in major development is claimed; some management control tools are discussed and shown to be vital engineering tools as well. Finally, increased attention to system engineering techniques and experiences in the engineering discourse in our community is encouraged
