摘要:

针对现有信号级协同抗干扰方法无法实现恒虚警鉴别的问题,提出了一种新的单脉冲回波数据下基于目标幅度比特征差异的有源假目标鉴别方法,通过对目标在各接收站中幅度比的随机分布进行理论分析,可在保证预设假目标误判概率的情况下,利用多维空间门限检测方法进行真假目标鉴别.仿真结果验证了这种方法的可行性和有效性.

Abstract:

Cooperation in multiple-radar has become an important trend in radar deception electronic counter-countermeasure. To solve the problem that the existing signal fusion-based methods cannot achieve a constant false alarm rate, this paper proposes a novel target discrimination method based on the difference in amplitude ratio feature. By the analysis of the random distribution of target amplitude ratio, multiple-dimensional test threshold is applied to discriminate the detected targets under a preset false alarm probability. Simulation results verify the feasibility and effectiveness of the proposed method.
