METHOD OF EVALUATING PARAMETERS OF TRAJECTORY OF RADIO-FREQUENCY RADIATION SOURCES IN TWO-POSITIONED PASSIVE GONIOMETRICAL RADAR STATION Russian patent published in 2005 - IPC

FIELD: radar detecting systems.

SUBSTANCE: method can be used for evaluation of parameters of parameters of movable radio-frequency radiation sources (RFRS). Angular coordinates of RFRS and coordinates of receiving positions (RP) and coordinates of RFRS are calculated in rectangular coordinate system. To estimate coordinates and projections of speed vectors of RFRS at axis of rectangular coordinate system the adaptive algorithms of α,β-filtration of results of generalized metering are used. Adaptation has to be the selection of values of gain factor in algorithms of filtration dependent on meanings of current errors of generalized metering provided by mutual movement of RP and RFSR. Filters can be reorganized easily by changing only two factors of amplification. Parameters of motion of RFRS can be estimated with specified level of estimation level; the errors do not depend on position of RFRS relatively RP.

EFFECT: improved precision.
