Construction of Multistatic Radio Receiving System for Research Purposes at the Przasnysz Airfield

The paper presents the technical assumptions and results of constructing a multistatic radio receiving system built at the airfield owned by the Warsaw University of Technology in Przasnysz, Poland. The purpose of the system is to enable various research and development works on sophisticated signal processing techniques with the multistatic radio signals reception, such as passive emitter tracking or passive coherent location. The system consists of four receiving stations in different locations. In each of them, there is an antenna mast with radio receivers and computers allowing to process recorded signals. A unique feature of the system is to ensure the reception of signals in the frequency band from approx. 85 MHz to approx. 3 GHz, which was achieved by using three circular antenna arrays operating in different bands.
