ERROR ANALYSIS OF SYSTEM FOR TEMPORAL–SPATIAL CHARACTERISTICS MEASUREMENTS OF LINEAR ULTRASOUND PHASED ARRAYS
Abstract:

The article considers ultrasound information measurement system for spatial-temporal characteristics measurements of linear ultrasound phased arrays in emission mode. Amplitude and phase errors of multichannel block and receive channel for impulse signals were analyzed.
