Multistatic Radar Detection and Tracking of Drones is a work by Marc Schneebeli, Andreas Leuengerger, Urs Siegenthaler, and Peter Wellig.

The SAMURAI multistatic C-band radar system was initially developed as a technology demonstrator for drone detection within a range of up to 5 km. It comprises two receiving nodes with a digital beamforming antenna and a phased array transmitting node employing a fast scanning pattern to illuminate the observation area. The radar signals are transmitted as linear frequency-modulated (LFM) pulses, enabling high-resolution range scanning through subsequent pulse compression. With over 100 W of transmit power in a narrow beam, the system exhibits high sensitivity crucial for detecting objects with small radar cross-sections.

Operated in a multistatic configuration, where nodes are distributed around the area of interest, the system benefits from redundancy and avoids zero Doppler conditions. This setup also ensures a more uniform signal-to-noise ratio (SNR) distribution across the observation area than classical monostatic radars. Precise alignment and calibration of multiple receive nodes are essential for successful track fusion algorithms, demonstrated through simulated and real targets such as drones and vehicles.

Geometric calibration using non-collocated target simulators has proven effective for achieving the required range and directional calibration accuracy. The system has undergone field campaigns for dron detection in various terrains, including mountainous and urban environments. Real drones and simulated targets generated by multistatic target generators were used to evaluate the system’s detection capability and track generation, with tracks from multiple receiving nodes fused in real time to provide continuous drone tracking even in aborted track generation on one receiver.
