Testing a multistatic C-band radar with a target simulator

A multistatic active surveillance radar system has been developed under the project name SAMURAI (Swiss African Multistatic Radar Initiative). The system comprises of one TX node and two RX nodes and works at C-band frequencies. A phased array on transmit and digital beamforming on receive enable the radar's scanning capabilities. The system was tested in a two-weeks period taking place in November 2019 in Thun, Switzerland. The system was initially tested in the laboratory, followed by field tests with a radar target simulator and finally a series of drone flights were executed. A specific C-band multistatic target simulator was built in order to fully exploit the system's capabilities.
