摘要
DBS(多普勒波束锐化 )是提高机载雷达横向分辨率的一种技术。本文分析了DBS的信号模型 ,提出了一种补偿技术可以有效提高大斜视 (例如 80°)时DBS分辨率。
DBS (Doppler Beam Sharpening) is a technique to improve the cross range resoluti on of airborne radar. In this paper, the signal model of DBS is analyzed and a k ind of compensating technique is suggested which can effectively improve the res olution of high squint DBS (for example 80°).The results of simulation and the processing results of real data show that it can effectively improve the resolut ion of DBS.
