While Doppler Active Radar Seeker (ARS) could be aided SINS by beamvelocity all The Times and remedy the BDS's default of lacking velocity information and continual working ability.
The estimated velocity increased with the decrease of Angle between the ultrasonic beam and blood flow.
随着超声波束与血流角度的减小，检测到速度增加。

The computations show that the foundation elasticity stiffness abrupt change has greater influences on beam vibration. This influences increase with increase of the velocity of the moving loads.
