enveloping k element, where Np is chosen on the
basis of allowable PI suppression reduction, there
at outputs of
measured is interference power
(57) Abstract:
FIELD: radio engineering.
SUBSTANCE: in suppression method of
interference representing passive interference (PI)
with unknown parametres, from received signals and
interference in N repetition periods of coherent
block, where N?2, there formed are references of
complex envelope xi?,?k, where i - number of
repetition period of coherent block, 1?i?N, k number of range element; as per references of
complex envelope in window of Nw range elements
enveloping k element there formed are evaluations of
correlation parametres of interference, which are
used to determine weight ratios of rejector filter to
the input of which there supplied are references of
complex envelope xi?k; at that, references of
complex envelope xi?,?k? are also supplied to M
additional rejector filters the weight ratios of
which are obtained by using the evaluations of
correlation parametres of interference in the
appropriate M windows of the size which is less than
Nw, and consisting of range elements enveloping k
element; then, in window from Np range elements
additional rejector filters, where j=1,?,M - number
of additional rejector filter, and interference power
at the output of the above rejector filter; r
filter is chosen from additional rejector filters,
where 1?r?M with minimum evaluation of
interference
power
at
its
output
after that, the following
condition is checked:
coefficient the value of which is determined with
allowable reduction of suppression of PI which are
homogeneous as to range, depending on the fact
whether this condition is met or not; mixture of
signals and suppressed interference is picked up from
the output either of r additional rejector filter or
the above rejector filter.
EFFECT: improving suppression of passive
interference which is non-homogeneous as to range.
