摘要
在水声对抗中,为了有效对抗假目标和准确判别目标尺度,提出了一种具有较高时-频联合分辨力和抗混响能力的LFM-Costas编码信号形式。并在浅海混响信道模型和目标多亮点模型基础上研究了LFM-Costas编码信号的目标尺度判别性能。通过仿真和海上试验,表明LFM-Costas编码信号在混响背景下能准确判别目标尺度,具有一定的工程应用价值。
In order to distinguish the false target or acoustic bait and estimate precisely the target scale, a new pulse coding waveform which having nearly ideal range-Doppler ambiguity properties is proposed. Then, the target scale recognition model of the pulse coding waveform is constructed. The ability and the stability of the target scale recognition algorithm are mainly researched, and found to get clearly multi-highlight of the target. The simulation and the sea trial results show the validity of the method.
