独立分量分析在雷达抗干扰处理中的应用

在实战过程中,干扰环境瞬息万变雷达工作环境的恶化使现代雷达系统面临着严峻挑战多数雷达都要求具有从强干扰环境中检测目标和提取目标参数的能力.这要求雷达应具有灵活的环境适应能力和抗干扰能力.为了对雷达信号在不同噪声环境下进行处理,提出采用基于高阶累积量张量对角化的独立分量分析方法.仿真结果表明,该方法可以很好地分离出各种不同调制方式下的连续波雷达信号,对雷达抗干扰具有有效性.

Independent Component Analysis Applied in the Processing of Radar Anti-interference

In the process of actual combat,with the interfering environment changing,the deterioration of radar working environment makes the modern radar system face severe challenges.Most of the radars are required with the ability to detect the target and extract target parameter from the strong interfering environment.Namely the radar has a flexible response ability and anti-interference ability.The method of independent component analysis which is based on the diagonalization of high-order cumulant tensors is proposed to process the radar signal under the environment of different SNR of noise.The simulation results show that this method is a good way to separate different modulation mode of continuous wave of radar signal and this new radar anti-interference technology is effective.
