Passive radar technology represents a promising addition to conventional
radar systems. With increasing demands from economy and politics to completely
use the limited spectrum of the frequency bands limited for telecommunications
and location, the interest in this technology is increasing.
The aim of this research project is to establish the technology of location
using passive radar technology in civil air traffic control in Germany and to open
new areas of application.
To improve the detection performance, various options for setting up a
frequency-selective analog receiver for the FM band are being developed and
integrated into an existing passive radar system. For the highest possible
sensitivity, filtering in different stages of the receiver is essential.
However, this must be evaluated together with the frequency-converting stages
in the overall system context in order not to degrade the signal quality,
including through possible imperfections in the analog implementation. Furthermore,
attention must also be paid to an optimal balance between circuit complexity,
costs and compactness of the receiver. For this purpose, the receiver
architectures are first examined in system simulations and evaluated regarding
the requirements from the application. This is followed by a prototype
construction of the most promising concepts with metrological verification of
the individual components and evaluation of the entire system in a field test.
