| Abstract(in English) | TDOA (Time Difference of Arrival) localization estimates a target position from arrival time differences of radio signals by detecting the signals in a number of ground receiver stations. It is desired for aeronautical surveillance system to provide high performance aircraft positions compared with conventional radar. WAM (Wide Area Multilateration) using TDOA localization is able to achieve the high performance and has been implemented in Japan. In TDOA localization, position error increases rapidly outside the receiver collocation. So WAM receiver stations are generally collocated as surrounding the target coverage. However this collocation method brings a challenge as increasing the number of receiver stations according to the coverage expansion. On the other hand, TSOA (Time Sum of Arrival) localization estimates a target position using time sums from a pulse signal transmission time in a transmitter station to the signal arrival times reflected from the target in a number of receiver stations. It is expected that TSOA localization could mitigate position error, because TSOA has additional information as a signal transmission time compared with TDOA. This paper describes calculation methods and estimated errors for TDOA and TSOA. And evaluation results by computer simulation are indicated for improvement of position accuracy by TSOA. |
