MODE OF LOCATION TARGET(VARIANTS) Russian patent published in 2005 - IPC

Abstract RU 2254592 C1

FIELD: the invention refers to the technique of detection of a target and determination of the direction at a target.

SUBSTANCE: the mode is realized by way of receiving of ultra wideband impulses reflected from the target, of delaying them on various time multitude in various channels of surveillance and multi channel processing. In the first variant of the current mode variation of the form of receiving impulses on a great number of discrete time positions are carried out by way of averaging-out by channels of surveillance at known direction of incoming reflected impulses in a beforehand designed control sector and then found valuation of the form of receiving impulse is used as a base signal in multi channel correlation processing. In the second variant valuation of magnitude of receiving impulse is formed in concrete moment of time for each base direction in beforehand given angular sector of control, valuation of the form of the receiving impulse is found according to formed valuations of magnitude 0f the receiving signal for various discrete moments of time; found valuation of receiving impulse is used as a base signal in multi channel correlation processing; out of multitude of results of correlation processing correlation maximum is chosen. This maximum is used as preliminary threshold decision statistics in the procedure of detection of the target; the direction of incoming reflected impulses with the help of interpolating valuation of the position of the correlation maximum in the environs of that base direction for which the largest result of multi channel correlation processing.

EFFECT: the use of this invention at location of a target with the help of ultra wideband impulses allows to receive signals incoming not only from in advance chosen base directions.
