Method of Calculating Desynchronization of DVB-T Transmitters Working in SFN for PCL Applications

Sensors (Basel). 2020 Oct 12;20(20):5776. doi: 10.3390/s20205776.

Abstract

This paper presents a novel method of calculating desynchronization between transmitters working in a single frequency digital video broadcasting-terrestrial (DVB-T) network. The described method can be a useful tool for enhancing passive radar operations and improving passive coherent location (PCL) sensors to correct their measurements of target localization. The paper presents the problem of localizing DVB-T transmitters utilized by passive radars, and proposes a novel method based on Time Difference of Arrival (TDoA) techniques to solve the problem. The proposed technique has been validated using real signals collected by a PCL sensor receiver. The details of the experiment and extensive result analysis are also contained in this article.

Keywords: DVB-T; SFN; TDoA; passive radar.
