Moving Target Detection by Using New LTE-Based Passive Radar

This paper examines the feasibility of Long Term Evolution (LTE)-based passive radar for detecting ground moving targets. Specifically, the focus of this paper is to describe the proposed LTE-based passive radar system and to conduct an experiment using a real LTE eNB transmitter as an illumination source. Seven scenarios were carried out to investigate the detection performance of the proposed system on ground moving targets with different speeds, trajectories and range. In addition, multi-target detection was also tested. The experimental results showed that the LTE-based passive radar system has the capability to detect typical ground targets like cars, motorbikes and humans moving at different trajectories. LTE is a new communication system and very few experimental result with real LTE signal has been published, thus the result and analysis from this paper will complement the technical readiness of the so called LTE based passive Radar. The positive results opened up a new frontier for passive radar systems to be used in many potential applications, including security, border protection, microwave fences, monitor of buildings and others.
