The result obtained states clearly that intermediate-range force, in the case of linear approximation, effects only radial acceleration of test particle rather than effects Lense - Thirring precession angular velocity of it.

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.

To the defect of Bearings only(BO) method which have long convergence time and large location error,this paper put forward a new single observer passive ranging and location method,which used bearings and its changing rate,radial acceleration information.

The result shows that the influence of gravitational settling and radial acceleration cannot be tolerated when wind speed of the separator inlet is low and the diameters of the solid particles are large.

Moreover,the components of the radial acceleration are theoretically derived,and the processing methods such as the signal sampling,the dynamic marking and storing,the noise removing,the slope comparison and the onset detection of braking operation are described.

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.

A phase method of measuring the radial acceleration of an aerodynamic object, used to increase the coherence interval of the reflected signal is proposed.

Briefly introducing the principle of operation of the sliding-vane rotary flowmeter,a reasonable design of the chamber profile in this kind of flowmeter is suggested in this paper with the intention of meeting such technical requirements as higher metering accuracy and less counting loss,wider metering range,less pressure loss,lower vibration and noise,steady rotation and less metering error due to the viscous property of the fluid metered.For the reason given above,the cycloid,taken as a transition curve of the chamber profile connecting two arcs with different curvature radii,is a substitute for the elliptic curve proposed in an earlier paper[1],thus preventing the impulse due to the radial acceleration caused by the elliptic curve.The theoretical and practical formulas of the chamber profile are shown as in formulas (6),(9) and (11) respectively,and the oscillating angle (pressure angle)λ and the minimum width of sliding-vane are also given.Finally,the possibilities of the smooth motion of sliding-vane and of the use of form milling to manufacture the chamber profile are also discussed.

: It is often troublesome, or even difficult, for the narrow band system in a coherent-pulse instrumentation radar to precisely track the radial speed of the target under conditions of low pulse repetition frequency of the radar and high speed and acceleration of the target.A method is given in this paper to bring about an all digital tracking system on the basis of modified DFT. Such system can track not only the radial speed of the target, but also its acceleration directly in conditions of low repetition frequency and high target speed and acceleration.The first part of the paper describes the influence of target radial acceleration on DFT. the modified DFT which can eliminate the said influence, and the two dimensional response characteristics of the frequency and the frequency changing rate of this modified DFT. The second part explains the method of eliminating speed ambiguity by repetition frequency agility. This method is based on solving residual equations for root and does no depend on target range information. The third part deals with the narrow band tracking loop based on modified DFT. Two dimensional error characteristics of the frequency and the frequency changing rate are presented, and a block-diagram of the system is also given.The author has conducted mathematical simulation of the above system. The results show that the accuracy in the measurement of radial speed and acceleration is quite satisfactory under the condition of comparatively low signal-noise ratio.
