Multi-sensor Reference Diversity for Improved OFDM Signal Reconstruction
2017 IEEE RADAR CONFERENCE (RADARCONF)(2017)
Abstract
Passive radar system performance is depending strongly on the quality of the received reference signal of an illuminator of opportunity. For digital transmitters decoding and re-encoding the digital signal allows the reconstruction of a noise-free replica of it. With increasing disturbances in the reference signal the error rate of the decoded information increases and leads to an inaccurate reference signal. We propose a method to use diverse reception from multiple sensors to optimize the reconstructed reference signal. Simulations and results from a multi-sensor system located in a wind park demonstrate its potential.
