METHOD FOR DETERMINATION OF COORDINATES OF EACH OF M ACTIVE OBJECTS Russian patent published in 1996 - IPC

FIELD: radio engineering. SUBSTANCE: method involves subsequent emission of signal by each of m active objects in turn, reception of emitted signals by master beacon, storing phase, delay and repeated emission of signals, which are received from each active object as well as reception of repeated signals from each active object by first and second slave beacons, storing their phase, delay, their repeated emission, reception by k-th active object of emission signals which we repeated by first and second slave beacons and emitted by k-th active object, detection of distance of k-th object to first and second slave beacons. In addition k-th active object receives signals which were emitted by all m active objects and repeated by master and first and second slave beacons. Distance to first and second slave beacons is calculated using equation , where (τ_AO-M+τ_M-AO) is delay for signal which has traveled from active object to master beacon and back; is difference between delays when signals travel from master beacon to active object through slave beacon and directly; is average for difference between delays for signals from master beacon to active object when signals from i-th object are received. EFFECT: increased precision. 5 dwg
