DEVICE AND METHOD OF RESOLVING AMBIGUITY FROM ESTIMATE OF DIRECTION OF ARRIVAL Russian patent published in 2015 - IPC G01S3/802 

FIELD: physics, computer engineering.

SUBSTANCE: device (100) for resolving ambiguity from an estimate (105) DOA ( $$\widehat{\phi }$$ _amb) comprises an analyser (110) for the DOA estimate for analysing the estimate (105) of DOA ( $$\widehat{\phi }$$ _amb) to obtain a set (115) of ambiguous analysis parameters ( $$\tilde{\phi }$$ _I… $$\tilde{\phi }$$ _N; f( $$\tilde{\phi }$$ _I)…f( $$\tilde{\phi }$$ _N); f_enh,I( $$\widehat{\phi }$$ _amb)…f_enh,N( $$\widehat{\phi }$$ _amb); g_P( $$\tilde{\phi }$$ _I)…g_p( $$\tilde{\phi }$$ _N); D( $$\tilde{\phi }$$ _I)…D( $$\tilde{\phi }$$ _N)) by using bias information (101), wherein the bias information (101) is the relationship ( $$\widehat{\phi }$$ ↔φ) between a biased ( $$\widehat{\phi }$$ ) and an unbiased DOA estimate (φ), and a unit (120) for resolving ambiguity in the set (115) of ambiguous analysis parameters ( $$\tilde{\phi }$$ _I… $$\tilde{\phi }$$ _N; f( $$\tilde{\phi }$$ _I)…f( $$\tilde{\phi }$$ _N); f_enh,I( $$\widehat{\phi }$$ _amb)…f_enh,N( $$\widehat{\phi }$$ _amb); g_P( $$\tilde{\phi }$$ _I)…g_p( $$\tilde{\phi }$$ _N); D( $$\tilde{\phi }$$ _I)…D( $$\tilde{\phi }$$ _N)) to obtain an unambiguous resolved parameter ( $$\tilde{\phi }$$ _res; f_res, 125).

EFFECT: designing a device for resolving ambiguity.
