摘　　要：针对相控参量阵声呐发射系统体积和质量大,难以搭载于水下小平台使用的问题,重点研究相控参量阵声呐发射系统的小型化、高集成度设计技术,设计并实现一种小型相控参量阵声呐发射系统。首先,基于发明问题解决理论中的剪裁思想,简化设计D类发射机功率放大电路的结构,减小多通道发射系统的体积。其次,联合磁芯几何常数法和脉冲变压器设计技术设计微型变压器,减小变压器体积的同时提升系统功率密度。与传统设计方法相比,系统电路整体体积缩小了24.6%,功率密度提升了27.3%。实测相控角度误差不超过0.3◦,参量阵原频声源级可达236.7 dB,差频声源级可达200.5 dB,以小型化发射系统实现了相控参量阵的精准相控发射和高原频声源级输出。In order to solve the problem of large volume and high weight of phased parametric array sonar emission system,which is difficult to carry a small underwater platform,this paper focuses on the miniaturization and high integration design method of phased parametric array sonar emission system.A small phased parametric array sonar emission system is designed and implemented.Firstly,based on the tailoring idea in the theory of inventive problem solving(TRIZ),the structure of the power amplifier circuit of class D transmitter is simplified and the volume of the multi-channel transmitter system is reduced.Secondly,the miniature transformer is designed by combining the core geometric constant method and the pulse transformer design technology to reduce the transformer volume and improve the power density of the system.Compared with the traditional design method,the overall volume of the system circuit is reduced by 24.6%,and the power density is increased by 27.3%.The measured phase control angle error is less than 0.3◦,and the original frequency sound source level of the parametric array can reach 236.7 dB the differential frequency source level can reach 200.5 dB.The accurate phase-controlled emission and high original frequency sound source level output ability of the phased parameter array are realized by a miniaturized transmission system.
