Costas DFC-Based Random Stepped Wideband Waveform for Interference Countermeasure in SAR Imagery
Interference in SAR imagery will induce false targets or form a mask in specific areas to prevent accurate scene assessment. Traditional anti-jamming methods based on waveform agility require a trade-off between anti-jamming performance and imaging ...
