摘要：
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. © 2017, Science Press. All right reserved.
