有源拖曳式诱饵是一种典型的双点源角度欺骗干扰,而且是一种主瓣干扰模式。为了提高导引头雷达抗拖曳式诱饵能力,首先,利用四通道单脉冲系统进行了诱饵辨识算法的验证;然后,从主瓣干扰抑制角度提出了一种自适应一维保形测角算法,并且对这种算法进行了理论推导和仿真验证;最后,给出了抗拖曳式诱饵的系统处理流程。仿真与试验数据证实了上述方法的可行性和有效性。

Towed radar active decoy(TRAD)is a typical angle deception jamming and mainlobe jamming. To improve the anti-TRAD ability of radar seeker, Firstly, the experiments on decoy identification by four-channel monopulse system are verified; Secondly, from the idea of mainlobe jamming suppression, the adaptive angle estimation algorithm is studied in this paper. Moreover, the system processing flow is proposed. The results indicate that the proposed methods are effective.
