跟踪干扰双曲线在跳频通信中的应用

Application of Following-jamming Hyperbola in Frequency-hopping Communications

针对中、低速跳频电台跟踪干扰问题,通过对跟踪干扰方程的分析,推导出了跟踪干扰无效区边界的一种新的表达式———跟踪干扰双曲线方程,重点分析了该双曲线的特点及影响因素,并讨论了跟踪干扰双曲线原理在实际装备中的应用及其扩展等问题。仿真与分析结果表明,根据跟踪干扰双曲线选择抗干扰措施更直观、更简单。

By transfiguring the following-jamming equation of communication , based on the is- sue of the anti-following-jamming about the slow frequency-hopping（FH） communication, a new equation or the following-jamming hyperbola equation for the boundary of the non - jamming area is deduced. The characteristics of the following- jamming hyperbola and the factors influencing the geometrical configuration are analysed, some practical problems about the application of the following-jamming hyperbola principle in the equipment and its extension are discussed. Simulation and analysis show that choosing anti-following-jamming measures by follow- ing-jamming hyperbola is more simple and direct than other methods.
