Abstract

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.
