In this paper, the problem of radial acceleration estimation in one pulse was dealt with based on Hough-Ambiguity transformation, and then acceleration was estimated.

Radial acceleration of radar and target is a important character of the relative movement of them and can enhances maneuvering target tracking and target identification,so study on radial acceleration estimation directly from radar echo is needed.

In the post signal processing of CW radars,when the radial acceleration of the target is big and the SNR is low,most methods to estimate it are incompetent for getting the precise result.

This paper puts forward the pseudo-acceleration correction self-adaptive α-β filtering algorithm pointing to the defect of the pseudo-acceleration self-adaptive α-β filtering algorithm without correction under current spherical coordinate.

The use of the radial velocity to improve the performance of target tracking;

The radial velocity of flow field in hydrocyclones has great influence on the particle radial movement, which decides the degree of resisting particle radial movement and the diameter of the minimum particles the hydrcyclone can separates.

Results show that the distribution of radial velocity of wide spaced two jet and four jet impinging streams has relation to d/L , the maximum radial velocity has relation to u 0 d/L , and the radial distance of the position of the maximum radial velocity is directly proportional to L .
