The passive synthetic aperture antenna array (PSAAA) technology is inspired by the idea of synthetic aperture sonar and synthetic aperture radar, which is a new method used to the passive radar source localization using only one small aircraft. Virtual time difference of arrival (VTDOA) estimation is critical for the PSAAA technology, it is defined as the time difference of the radar pulse transmission...
This paper considers the problem of how to accurately and passively localise the hostile radar position based on only one small size aircraft. Inspired by Synthetic Aperture Sonar (SAS), Synthetic Aperture Radar (SAR) and multi-static passive radar, a similar concept of Passive Synthetic Aperture Antenna Array (PSAAA) is introduced into this paper. The same single receiver carried by one small aircraft...
