Over the next decade the passive radar technology market has been forecast to increase at a compound annual growth rate (CAGR) of almost 36%, with investments into the industry forecast to account for more than $10 billion in revenue.
The passive radar market is still in its infancy, and few companies have developed effective, marketable systems. However, as the technology becomes more sophisticated and affordable, more and more competitors can be expected to enter the market, particularly in defense and homeland security.
Passive radar systems encompass a class of radar systems that detect and track objects by processing reflections from non-cooperative sources of illumination in the environment, such as commercial broadcast and communications signals. It is a specific case of bistatic radar, the latter also including the exploitation of cooperative and non-cooperative radar transmitters.
Passive radar is different from traditional forms of radar in that it does not emit any electromagnetic radiation. Instead, it relies on reflections from other electromagnetic signals in the atmosphere in order to provide a radar picture.
Research on passive radar systems is of growing interest throughout the world, with various open source publications showing active research and development in the United States (including work at the Air Force Research Labs, Lockheed-Martin Mission Systems, Raytheon, University of Washington, Georgia Tech/Georgia Tech Research Institute and the University of Illinois), in the NATO C3 Agency in The Netherlands, in the United Kingdom (at Roke Manor Research, QinetiQ, University of Birmingham, University College London and BAE Systems, France (including the government labs of ONERA), Germany (including the labs at FGAN-FHR), and Poland (including Warsaw University of Technology).
There is also active research on this technology in several government or university laboratories in China, Iran, Russia and South Africa. The low cost nature of the system makes the technology particularly attractive to university laboratories and other agencies with limited budgets, as the key requirements are less hardware and more algorithmic sophistication and computational power.
According to a recent report, 'The Military and Civil Aviation Passive Radar Market: 2013 - 2023,' the flexibility of deployment, together with stealth and surveillance capabilities will drive passive radar investments to comprise nearly 41% of the total military radar spending between 2013 and 2023. Cost efficiency, spectrum congestion and emerging urban applications are the key drivers impelling passive radar investments in civil aviation.
