通过研究潜艇拖曳环天线的热噪声 ,分析了天线构造参数对热噪声性能的影响。为了获得最小热噪声ENF ,在电缆浮力条件下对天线参数进行了最优化。在满足天线主要电参数的要求下 ,探讨了利用最优化参数的可行性。分析结果表明 ,设计拖曳环天线的关键和难点是获得高可逆磁导率的磁芯 ,并给出了解决这一问题的途径。
According to study the thermal noise generation of a towed loop antenna,the influence of the antenna's construction parameters on the thermal noise has been analyzed. To minimize the thermal noise ENF under the buoyant condition of the cable,the optimization of the antenna parameters is obtained. This paper discusses the feasibility to apply the optimization of parameters. It is shown that the key and difficult point to realize the optimization of parameters on the design of the towed loop antenna is that of the core's high reversible permeability,and some methods to resolve the question have been given.
