Dynamic depth focusing

WebDynamic Depth Focussing Dynamic Depth Focussing or DDF is a method of extending a single point of focus to a focal range. DDF is purely artificial and is always calculated on … WebA new method with real-time Dynamic Depth Full Focusing (DDFF), in emission and reception, is proposed in this work. It is called Total Focusing Phased Array (TFPA) because it uses concepts of TFM and PA. Omnidirectional emissions are used to create a synthetic aperture as in TFM, while beamforming is carried out along scan lines as in PA ...
