Title:
RF放出体の可搬型反復地理的位置検出
Document Type and Number:
Japanese Patent JP2010515052
Kind Code:
A
Abstract:
Iterative geolocation of a stationary RF emitter through the use of TDOA may include the use of a single portable geolocation (e.g., TDOA) sensor, a pair of portable geolocation sensors and three of more portable geolocation sensors. Adding portable geolocation sensors to the iterative process reduces the constraints on the signals to be located as well as providing a reduction in the number of iterations required to obtain improved location accuracy.
