Phased array technology in Australia

Australia has been developing and fielding phased array applications since the early 1950s. The application areas range from radio astronomy and atmospheric sciences, through over-the-horizon radar, surface wave, microwave ship and airborne systems. Given Australia´s unique geographical size, position, single continent and national identity, it is not surprising that much of this effort has been focussed on long range over- the-horizon technology, both for environmental observation and surveillance of the extensive land and maritime regions of national interest and responsibility. This discussion will draw focus on just a few of the historical and current programs finishing with an overview of the current application of active phased array developments for ship defence.
