摘要

摘要: 该文提出了一种利用极化信息对机载拖曳式诱饵进行检测和抑制的方法。建立了拖曳式诱饵干扰条件下雷达目标的全极化雷达回波模型，分析了转发式诱饵干扰和雷达目标在单脉冲雷达测角系统中不同极化通道响应函数的差异，利用存在和不存在干扰时测得的目标极化散射矩阵散度的差异，提出了一种转发式拖曳诱饵存在性的检测方法，并设计了相应的干扰抑制算法。仿真实验验证了该方法的可行性和有效性。该文的研究工作为有效检测与抑制拖曳式诱饵提供了一条新的途径，对提高雷达末制导系统在干扰条件下的精确打击能力具有重要参考意义。

Abstract: This paper focuses on the countermeasures of airborne towed radar active decoy.Moreover, a detection and suppression scheme of Towed Radar Active Decoy (TRAD) using polarization information is proposed.A full-polarization radar echo model with the presence of jamming is established.Furthermore, based on a monopulse radar angle measurement system, the difference between the characteristics of TRAD and radar targets in different polarization channels is analyzed.A detection scheme is proposed using the differences of target Polarization Scattering Matrix (PSM) divergence with the presence and absence of TRAD.Subsequently, the corresponding jamming suppression algorithm is developed.The efficiency and advantages of the proposed algorithm are validated via theoretical analyses and simulation studies.This paper provides an effective method to detect TRAD and can provide a significant reference for improving the precision strike of terminal guidance radar under jamming.
