摘要
针对杂波与干扰复合的复杂环境,研究了雷达抗干扰及反杂波处理兼容性设计问题。首先,分析了传统旁瓣对消(SLC)采样及对消处理方法在应对杂波环境时存在的性能不足;然后,基于仿真及实测数据,对比分析了"先做动目标显示(MTI),再做SLC"、"先做SLC,再做MTI"等不同处理方法的抗干扰性能;最后,针对不同的应用场景,提出了雷达系统SLC及MTI兼容性优化设计方案,对雷达系统设计研制具有重要的参考价值。
The compatibility design of radar anti-jamming and anti-clutter processing,especially in complex environment comprising clutter and jamming is studied in this paper.Firstly,the deficiency of traditional sidelobe cancellation(SLC)technology is analyzed when dealing with noise jamming in clutter.Secondly,the anti-jamming performances of two typical signal processes are compared with simulation and real data,which are called"executing moving target indicator(MTI)before SLC"and"executing SLC before MTI"respectively.Finally,the optimized compatibility design of SLC and MTI is proposed dealing with different conditions,showing great significance to radar system design.
