摘要
作为主动声纳系统设计的三大要素之一.主动声纳波形设计在主动声纳系统设计中占有重要的地位。主动声纳信号波形不仅决定了接收信号的处理方式,还直接影响到系统的分辨率、测量精度、抗干扰能力以及目标跟踪性能等各个方面。利用信号的Q函数和互模糊度函数,研究信号的抗互相能力和声兼容性能。并通过实际的海试数据分析,验证了这种分析方法的可行性、有效性和正确性。
As one of the three most principal factors in active soanr system design, waveform design plays a very important role, The transmitted waveform not only determines the signal processing schemes, but also the system＇s velocity/range resolution, parameters estimation precision, reverberation suppression capabilities and tracking performances etc. In this paper, the reverberation suppression capabilities and acoustic tolerance performance of active sonar waveforms are analyzed by means of the Q-function and cross-ambiguity function. At the same time, practical sea trial data analyses are made to prove the feasibilities, correctness and effectiveness of these analyses.
