Multistatic Multiband Passive Radar - Architecture and Sensor Cluster Results

Passive radar technology is a demanding technology for air surveillance and homeland defence. This paper discusses briefly the fundamentals of multistatic passive radar and explains the system architecture of a state-of-the-art multistatic multiband passive radar developed by Hensoldt Sensors. The system architecture and relevant system components like the antenna, the receiver and the multi-hypothesis tracking system are introduced. Thereafter single-sensor results and results of a measurement campaign with a sensor cluster, comprising four passive radar sensors, are presented. The shown results are proving the feasibility of passive radar as a powerful sensor network for future air surveillance systems.
