本文论述了一种具有恒定增益的童通式转发器。对于机载应用而言,它能以足够的功率放大和返回雷达信号,提供对放大信号经过适当调制的防御性电子对抗措施;对于非机上的应用,它的作用是通过放大和返回与所保护的目标的回波与运动特性相似的雷达信号,以提供欺骗敌方雷达的假目标。文章还就有关的隐身技术作了阐述,引用了对反射器形状按其对雷达散射截面的贡献和对频率与入射角的依赖关系分级,以便按优先次序缩减雷达散射截面。文章提出了根据隐身平台设计所达到的雷达散射截面水平,来选择作为频率函数的转发器的系统增益,并建立了转发器所保护的平台的最大雷达散射截面,饱和距离与照射雷达的频率、功率之间的关系,以及转发器系统增益与饱和距离之间的关系。
This article discusses a Tong Tong transponder with a constant gain. For on-board applications, it amplifies and returns the radar signal with sufficient power to provide defensive electronic countermeasures that are properly modulated on the amplified signal. For non-on-board applications, it functions by amplifying and returning to the protected The target’s echo and motion characteristics are similar to radar signals to provide a fake target to cheat enemy radar. The article also elaborates on stealth technology, citing the contribution of reflector shape to its radar cross section and its dependence on frequency and angle of incidence in order to reduce the radar cross section in order of priority. In this paper, the system gain of the transponder as a function of frequency is chosen according to the level of radar cross section obtained by the stealthy platform design. The maximum radar cross section, the saturation distance and the frequency of the irradiated radar are established for the platform protected by the transponder. The relationship between power, and the relationship between the gain of the transponder system and the saturation distance.
