ADAPTIVE TELEMETRIC MEASUREMENT FILTER FOR OPERATION UNDER CONDITIONS OF A PRIORI UNCERTAINTY Russian patent published in 2020 - IPC G05B23/00 G01S13/526 

FIELD: shipborne engineering systems; shipborne armament.

SUBSTANCE: invention relates to processing telemetric measurements obtained in real time. Adaptive telemetric measurement filter is designed to isolate a useful signal with noise background, as well as estimating non-observed conditions in conditions of absence of reliable a priori information on noise parameters during solving tasks of positioning of controlled and unmanned sea-based devices. Said technical result is achieved by adding a divider, two covariance calculation units, two multipliers and one adder to the design of the known Kalman filter. Added units allow, during operation of adaptive filter, to determine values of filter gain amplitudes under conditions when true values of noise dispersions of measured signal are unknown.

EFFECT: main advantage of adaptive filter in comparison with existing filters is that it can be used in conditions of a priori uncertainty in real time for processing telemetric measurements, coming from objects moving at high speed and having stochastic nature, including non-stationary ones.
