This paper presents the preliminary results of target detection using a passive radar using skywave over-the-horizon radar (OTHR) as an illuminator of opportunity and a lightweight commercial software-defined radio (SDR) with a single compact antenna. First, the receiving station is shown. Next, the results of the radar pulse recognition and reconstruction are presented. The final results presented in this paper confirm that pulse signal passive radar processing allows for the detection and tracking of a non-cooperative target, which paves the way for the further development of OTHR-based passive radars.
