Design of a new airport surveillance radar (ASR-9)

The ASR-9 marks a significant departure from earlier ASR designs [1]. Major operational benefits are realized by applying modern digital technology and advanced processing concepts. It is evolutionary in that it retains the desirable features of its predecessors. This paper will focus on the principal characteristics that make its design unique. The following topics are covered: aircraft detection in clutter, range resolution, azimuth resolution, weather contouring, remote performance monitoring and control.
