Digital beamforming array response under conditions of limiting in element channels

, 1999
In Digital Beamforming arrays (DBF), array element outputs are heterodyned to zero IF, then converted to digital form and combined in a digital combiner. If this process is not linear, it gives rise to angle harmonics.

Variable delay CMOS implementation for ultrasonic beamforming

, 2003
An ultrasound imaging systems require high resolution and real-time processing. The real-time imaging can be achieved using a digital beamforming (DBF) method. One of the main important parts of the DBF is the real-time delay calculation.
