【摘要】 采用多种频域窗函数综合出了一组大时带积非线性调频脉冲压缩信号，其中一些窗函数的应用尚未见类似的研究报道。本文模拟分析了这类信号的分辨力和多普勒响应性能，并与实验结果进行分析比较，总结了设计大时带积非线性调频脉压信号窗函数的选择原则。该组信号应用于远程警戒雷达可收到增加检测目标动态范围而不降低作用距离的实效。更多还原

【Abstract】 A group of large time-bandwidth Product NLFM signals are synthesized with various window-functions in frequency domain, the analogous application of some window-functions have not been reported before. Meanwhile, the computer simulation results of the signal resolution and Doppler response are also discussed and compared with the actual experimental results. At last, the selection Principles of window designing large, time-bandwidth Product NLFM signals are generalized These signals can be used in long-range alarm radar and will increase the dynamic range of target detection without lowering the effectiveness of working distance.更多还原
