TELEVISION RANGE FINDER Russian patent published in 1997 - IPC

FIELD: electronic engineering. SUBSTANCE: television range finder reduces time of range determination due to introduction of two check selectors, two coordinators, subtracter, and decoder. First output of synchronizer is connected to first inputs of two units, series-connected delay lines the outputs of which are connected to first group inputs of electronic switches. Second group inputs of electronic switches are connected to first and second group outputs of decoder. Outputs of other television pickups are connected through first and second check selectors. First and second coordinators are connected respectively to first and second inputs of subtracter the group output of which is connected to group input of decoder. EFFECT: higher measurement results.
