Passive target localization using a geometric approach to the time-difference-of-arrival method / S. Wong, R. Jassemi-Zargani, D. Brookes, B. Kim, DRDC - Ottawa Research Centre.: D68-2/079-2017E-PDF
"Passive sensing offers a viable and effective means of detecting and geolocating small flying targets such as micro- and nano-drones by exploiting their radio-frequency signal emissions. Target location using the time-difference-of-arrival (TDOA) method is investigated. For target localization in three-dimensional space, a set of three non-linear TDOA equations is required. Each equation contains a TDOA measurement processed from signals detected by a pair of receivers. A system of four receivers is needed to generate three independent TDOA measurements. The solution to each TDOA equation is represented by a hyperboloid surface. The intersection of three hyperboloid surfaces is then computed to determine the target location. This geometric approach to solving the TDOA problem is taken in this study."--Abstract, page i.
