摘要
电子战数字接收机侦收脉冲信号时,由于窗函数失配而无法达到理论上测算出的检测性能。针对此,分析了脉冲检测时窗函数宽度和形状失配对数字接收机灵敏度的影响,给出了灵敏度边界条件;同时,也提出了一些建议,为最佳数字接收机设计提供了依据。
Electronic warfare （EW） digital receivers cannot achieve the traditional theoretical detec- tion performance due to window function mismatching. The effects on sensitivity of digital receiver from mismatching of window function and pulse widths are analyzed, and the sensitivity boundaries are derived. Furthermore, some suggestions are presented for digital receivers design with optimal sensi- tivity.
