本文结合本课题组在我所水池和哈尔滨附近的二龙山水库中测差频波声场特性时出现的伪声—假参频信号,较全面地分析了信号的发射系统、传播介质、接收系统中产生伪声的各种原因与鉴别方法,并提出了有效的防止措施,这将对从事参量阵研究工作者都有实际指导意义。 In this paper, we combine the false-false reference signal which appears in our pool and Erlongshan reservoir in Harbin near Erhai reservoir to analyze the signal transmitting system, propagation medium and receiving system The causes of pseudo-sound generation and identification methods, and put forward effective preventive measures, which will have practical guidance for those engaged in parametric array research.
