A BSS-based space–time multi-channel algorithm for complex-jamming suppression

Radar Main-Lobe Jamming Suppression Based on Adaptive Opposite Fireworks Algorithm

“…According to the fitness ( ) of the firework . Equation (15) and (16) are the calculation equation of the number of sparks. The calculation Equation of the explosion amplitude is expressed by formula (17).…”

“…jamming. Literature [16] introduces a space-time multichannel algorithm based on blind source separation to suppress the complex interference of the main lobe, which is saliently featured by the fact that it does not require prior knowledge on actual targets or interference, thereby making it easy to implement in engineering applications. Literature [17] proposes a method based on independent component analysis for the main lobe interference problem in passive bistatic radar (PBR).…”

Main lobe jamming suppression via blind source separation sparse signal recovery with subarray configuration

“…Recently, blind source separation (BSS) has been widely concerned to resist main lobe jamming [16–20]. BSS mainly utilises the independence between the target echo and the jamming signal to separate the target and jamming signals.…”

“…accurate angle and polarisation state of the jamming signal) and directly processes the received signal. The approaches in [16–20] only employ BSS to separate the jamming signal and the target echo, which, however, cannot derive the correct DOA.…”

High Precision Sparse Reconstruction Scheme for Multiple Radar Mainlobe Jammings

“…However, this method destroys the spatial information of the target. BSS methods have been widely used in resisting multiple mainlobe jammings [19][20][21]. However, these approaches only employ BSS to separate the jamming signals and target returns, which cannot derive the correct DOA of the target.…”
