The clutter is predicted exactly and subtracted from the input signal by RLS adaptive filter, leaving components of the target signal in the residual noise.

通过RLS自适应滤波器，背景杂波分量被准确地预测并从输入信号中去除，从而只剩下目标信号与残留噪声。

This paper realize the radar echo signal analysis and modeling from three aspects: contain the target echo, sea clutter, rain clutter and noise.

着重从目标回波、海杂波、噪声三个方面对雷达回波信号进行了分析和建模。

Sea clutter is the backscatter from fluctuant sea surface. Sea clutter is the major noise interference of seaborne radar.

海杂波指雷达波束照射到海面上后引起的后向散射杂波，是海防预警雷达的主要噪声干扰。
