METHOD FOR DETERMINING NUMBER OF TARGETS IN A GROUP Russian patent published in 2005 - IPC

FIELD: radiolocation.

SUBSTANCE: method includes analog-digital conversion of reflected from targets and received signal, calculating complex correlation sums of selection of received signal and support quadrature signals with values of parameter of resolution of support signal, taken on e even mesh, maximal by width intervals of values of resolution parameter, inside which all modules of correlation sums exceed threshold of detection, decision is taken about match of each local maximum to one target in the ranges, in which number of local maximums is more than one, width of range is calculated, inside which one local maximum is placed, decision about match of one local maximum to two targets is taken in case, if width of range is more than threshold width, in opposite case minimal non-square non-match of counts of complex correlation sums and count s of standard correlation sums of signal of one target are calculated, and decision is taken about match of local maximum inside range of one target in case, if non-match is less than non-match threshold, and two targets - in opposite case.

EFFECT: higher efficiency.
