Beacon Tracking Systems Simulation.
Colquitt,Elodie S · Defense Technical Information Center (DTIC) · 1977
The Beacon Tracking System is designed to determine the position of a beacon transmitter carried aboard a surface or air target using the Time-Difference-of-Arrival (TDOA) concept. Target position is computed based on a weighted least-squares solution of the TDOA data. A computer simulation of the system is used to investigate the system's sensitivity to several parameters. Sensitive parameters are shown to be: (1) receiver geometry relative to the target; (2) receiver position survey accuracy; (3) and loss of signal by one or more receivers during a track. (Author)
