METHOD TO DETECT LOCATIONS AND CAPACITIES OF SOURCES OF RADIATION BY SINGLE-POSITION LOCATION STATION Russian patent published in 2013 - IPC G01R29/08 G01S13/46 

FIELD: measurement equipment.

SUBSTANCE: method consists in breaking of a controlled area of space into resolution elements by location, identification of signal weakening coefficients due to propagation from each element of resolution to a receiving antenna array (AA) $$\alpha \left({\overrightarrow{r}}_k\right)$$ and time intervals of signal propagation from each element of resolution to each AA element τ_kn, where k - number of the resolution element, n - number of the AA element, determination of coefficients of spatial conversion of signals $$w_{kn}=\alpha \left({\overrightarrow{r}}_k\right)e^{-j\omega {\tau }_{kn}},$$ where ω - carrier frequency of signals of sources; j - complex unit, measurement of a spatial correlation matrix of received signals R_xx, making for all components z_im of this matrix the equations of the type $${\varsigma }_{\mu }=z_{mi}={\overrightarrow{\eta }}_{\mu }^T\overrightarrow{\xi },$$ where µ=(m-1)N+1, m - number of the line, number of the column, $${\overrightarrow{\eta }}_{\mu }={\left[w_{m1}{w}_{i1}^{*}{w}_{m1}{w}_{i2}^{*}\dots w_{m1}{w}_{iK}^{*}{w}_{m2}{w}_{i1}^{*}{w}_{m2}{w}_{i2}^{*}\dots w_{mK}{w}_{iK}^{*}\right]}^T,$$ N - number of AA elements, K - number of resolution elements $$\overrightarrow{\xi }={\left[{\xi }_1{\xi }_2\dots {\xi }_{K^2}\right]}^T$$ - vector, components of which are components of the correlation matrix of resolution element radiation, formation of the vector-matrix equation of measurements from the prepared equations, determination of the vector estimate $$\overrightarrow{\xi }$$ from it, formation of the estimate of the correlation matrix of resolution element radiation from the components of the vector estimate $$\overrightarrow{\xi },$$ determination of capacities and locations of radiation sources by diagonal components of the produced matrix.

EFFECT: simplified measurements and reduced time of measurements due to elimination of an operation of antenna directivity pattern formation in specified directions, increased information value of produced data due to estimation of mutual correlation characteristics of source signals.
