Analysis of the Performance of Digital Array Radar on Spatial ECCM

The advantages of spatial ECCM performance of digital array radar (DAR) are discussed. For practical consideration, a novel ECCM technique for ground based DAR is proposed. The novel technique is based on architecture of the multiple simultaneously DBF, which can improve the performance of the ECCM as well as the angle accuracy of the low-flying targets. The performance of the novel method is evaluated using measured data recorded by an experimental 3D DBF phased array radar. At the same time, the limitations of spatial ECCM performance of DAR are also discussed in this paper. It is believed that the research and the discussion in this paper would be helpful for understanding the development of the ECCM and the challenge of the DAR.
