GNSS-Based Non-Cooperative Air Traffic Situational Awareness

Kurzfassung

This work performs an initial feasibility assessment of a global navigation satellite system (GNSS)-based passive multistatic radar approach meant to enable non-cooperative air traffic situational awareness. First, the theoretical detection performance when assuming a long integration time is evaluated for both the bistatic and multistatic radar cases. Following this, the range and Doppler migration compensation approach needed to enable a high processing gain in practice is addressed and a multi-frame hybrid integration technique proposed. This approach builds up on our previous single frame long integration technique, corrects for the intra- and inter-frame range and Doppler migration components while allowing for different accelerations in each frame, therefore accounting for a geometryinduced relative jerk. Preliminary simulation results show the effectiveness of the proposed approach.
