radial filter

Then go to Filter > Blur > Radial Blur and apply a Zoom Blur.

然后转到过滤器>模糊>径向模糊和运用缩放模糊.

A new algorithm is developed to incorporate the radial velocity measurement into extended Kalman filter.

研究了一种把径向速度测量引入推广Kalman滤波（EKF）的新方法。

A new adaptive kernel function, named the radial parabola kernel ( RPK), is proposed, the RPK can adopt the optimizing method to filter cross-terms adaptively according to the signal distribution, obtain good time-frequency resolution, and offers improved TFD for a large class of signals.

该核函数可根据被分析信号的不同特性，采用优化方法自适应对模糊函数进行低通滤波，最大程度地滤除交叉干扰项，提高时频分辨率，具有对信号的广泛自适应性。
