Solid particle velocity measurement based on spatial filtering effect of electrodynamic sensor;

Based on the spatial filtering effect which occurs when oil/gas/water three phase liquid flow through the capacitance electrodes,the flow velocity in liquid and gas phase can be measured by frequency analysis?This method needs less measuring parameters and can be used to measure the component's velocity in multi-phase liquid for demand of real-time,on-line,continuous and non-intrude.

These equations include the effects of electron momentum spread, space-charge effects and wiggler taper governing the self-consistent evolution of TE mode and trajectories of an ensemble of electrons.

Computer Simulation for Spatial Filtering Experiment;

Spatial filtering in near field based on rotating and polarizing property of crystal;

Measuring velocity of glider on air track based on spatial filtering;

It adopts space filtering technique to achieve suppression of jamming signal by comparing the output amplitude from the receivers of the main and auxiliary antennas.

Beam pattern null in the direction of jamming is formed by space filtering and assisted receive channels to suppress the jamming.
