摘要: Radar target signals and chaff cloud
jamming signals have different characters by the wavelet transform.
The wavelet coefficients of radar target signals are highly
correlated with its near-and-near-scale wavelet coefficients,
however the correlativity between the wavelet coefficients of chaff
cloud jamming signals and its near-and-near scale wavelet
coefficients is less significant. Based on the binary-base discrete
wavelet transform and the correlation algorithm, the method of
target entropy to estimate standard variance of the jamming signals
and each scale is proposed to ensure reasonable threshold, to
suppress chaff cloud signals and finally to reconstruct mixed
signals by the improved spatially selective noise filtration (ISSNF)
method. The extensive simulation results show that the proposed
method can availably suppress chaff cloud jamming and decontaminate
target echo.
