| 摘 要： | 线性调频信号和二相编码信号在脉冲压缩雷达系统中使用较为广泛。分别对其进行分析后推导出一类线性调频 二相编码复合调制信号的时域表达式,使其兼有这两种信号的特点。对其进行仿真的结果表明,该复合调制信号容易产生并处理,其匹配滤波结果对多普勒频移也不敏感,但由于该信号的特殊性,常规的窗函数无法对其进行旁瓣抑制。采用了网络综合法抑制其旁瓣,效果十分理想。 |
| 关 键 词： | 线性调频 二相编码 脉冲压缩 旁瓣抑制 匹配滤波 网络综合 |

| Abstract: | Linear frequency modulation (LFM) signal and binary phased code (BC) signal are applied widely in pulse compression radar system. The time domain expression for a class of LFM-BC co-modulated signal that has some features of these two signals is proposed after the two signals are analyzed. The simulation results how that the signal is not only easy to be produced and processed, but also in sensitive to Doppler frequency shift after matched filtering, however, conventional window function is not effective for sidelobe suppression because of its particularity. So network synthesis is employed to restrain sidelobes and the final results are quite ideal. |
| Keywords: | linear frequency modulation binary phased code pulse compression sidelobe suppression matched filter network synthesis |
