摘要
为了减弱异步干扰脉冲对机载雷达的影响,提高机载雷达的抗干扰能力,首先使用自回归模型进行地杂波抑制处理,然后利用自回归模型的系数和杂波抑制剩余信号进行干扰脉冲的检测和判断。仿真结果表明,该算法可行且有效。
In order to weaken the effect of asynchronous impulse interference upon the airborne radar and to raise the interference-free capacity of the airborne radar,the auto-regression model is first used to suppress the clutters,and then the coefficients of the auto-regression model and the clutter suppression residual signals are used to carry out the detection and judgement of the impulse interference.The simulation results indicate that this algorithm is feasible and efficient.
