Passive radars are notoriously robust to jamming because the receiver location cannot be detected. Moreover, the use of OFDM based reference signals further improves the robustness against jammers.

Abstract

Passive radars are notoriously robust to jamming because the receiver location cannot be detected. Moreover, the use of OFDM based reference signals further improves the robustness against jammers. Nevertheless, recent papers have shown that deception/spoofing-type of jamming may still be possible. The idea was to use a target-on-board deception jammer aimed at deceiving the receiver by preventing it from precisely locating and identifying the target when passive radar imaging is used. In this paper, the same authors test the proposed approach by using a measured DVB-T reference signal. A realistic scenario is emulated by using a multichannel DVB-T signal (three DVB-T channels- A bout 24 MHz bandwidth).
