    摘要
  • 摘要: 在频谱拥挤环境下，同频窄带干扰对雷达系统目标探测性能有较大的影响。针对此问题，稀疏频率波形是一个好的解决方案。波形在频谱上稀疏分布的特性可以有效地抑制同频干扰，自相关函数的低旁瓣特性保证了雷达的探测性能。本文提出了一种应用互补码设计稀疏频率波形的方法。首先，考虑两个序列的自相关函数，利用互补码良好的自相关特性，建立目标函数；其次，采用功率与旁瓣两种约束分别设计稀疏频率波形，适应不同的场景需求；最后，通过数值仿真比较，分析旁瓣抑制性能，验证优化设计方法的有效性。
    Abstract: In the crowded spectrum environment, the interference of the same frequency narrow-band has great influence on the detection performance of radar system. For this problem, sparse frequency waveform is a good solution. The waveform has the characteristic of sparse distribution on the spectrum, which can effectively suppress the same frequency interference. The low sidelobe property of the auto-correlation function ensure the detection performance of radar. In this paper, a method of designing sparse frequency waveforms by using complementary code is proposed. Firstly, considering the auto-correlation function of two sequences, the objective function is established by using the good auto-correlation of complementary codes. Secondly, the sparse frequency waveform is designed respectively by using power and sidelobe constraints to adapt the different scene requirements. Finally, the performance of sidelobe suppression is analyzed by numerical simulation to verify the effectiveness of the optimization design method.
