中文摘要:
      针对使用多频信号的高速运动的前视主动声纳,对运算量小、较为实用的降维空时自适应抑制混响方法进行了研究,分析得出多频信号的混响空时二维分布特性,在此基础上提出了基于时空级联自适应处理非相干叠加多频信号混响抑制方法,仿真实验研究表明:该方法具有较好的多频信号混响抑制性能,而且大大降低了系统的维数和运算量,便于实际工程实现。
英文摘要:
      In multi-frequency condition,the space-time adaptive processing of less complexity(the cascaded time-space) is studied to suppress reverberation in active sonar.Based on which a method of noncoherent accumulation after space-time adaptive multi-frequency reverberation suppression is established.The simulation results show that the space-time adaptive approaches can suppress the multi-frequency reverberation effectively.
