  • 摘要: 為有效干擾SAR圖像CFAR檢測系統(tǒng)，該文提出基于間歇采樣重復轉(zhuǎn)發(fā)的SAR多假目標干擾方法，解決了傳統(tǒng)間歇采樣直接轉(zhuǎn)發(fā)干擾所形成的假目標少、干擾功率利用率低的缺點；在此基礎(chǔ)上，著重分析了多假目標干擾對SAR圖像雙參數(shù)CFAR檢測性能的影響。研究結(jié)果表明多假目標干擾在提高檢測門限的同時，有效降低了雙參數(shù)CFAR的檢測性能。最后針對雙參數(shù)CFAR背景窗口特點，采用多部分布式干擾機建立了2維網(wǎng)狀多假目標干擾應用模型，有效保證了背景窗口中假目標數(shù)量。理論分析和仿真實驗驗證了該干擾方法的可行性和有效性。
    Abstract: In order to destroy the detection performance of Constant False Alarm Rate (CFAR) detection system in SAR images, a new multiple false targets method based on intermittent sampling and periodic repeater jamming is proposed. The new method can solve the disadvantages of less false targets and lower jamming power utilization rate from traditional intermittent sampling direct repeater jamming. Then, the jamming performance of multiple false targets against Bi-Parameter CFAR (BP-CFAR) detection in SAR images is analyzed in details. The research result shows that multiple false targets can raise the detection threshold and weaken the detection performance of BP-CFAR. Finally, according to the characteristic of CFAR detection window, the application model of multiple jammers is established. The model can produce 2-D netted multiple false targets, so it can effectively guarantee enough false targets in detection window. Theoretical analysis and computer simulation justify the validity and the efficiency.
