Single receiver Long-Term Evolution passive radar system using signal reconstruction for moving target detection

This paper presents a single-antenna receiver passive radar system in the context of moving target detection such as trains, car, planes and UAVs, leveraging the long-term evolution (LTE) network as an illumination source. The proposed system uses signal reconstruction enabled by the telecom structure of the opportune signal in order to forego the use of a reference antenna. This presents the advantage of not relying on a physical signal for reference and its possible defect, potentially yielding better performances. The techniques introduced are validated through simulation and experiments. Moreover, a simplified passive radar system emphasises one of the key advantage of passive radar over other competing technologies for moving target detection: stealthiness and cost-effectiveness.
