A 2-D imaging procedure for ultrasonic nondestructive testing, exploiting pseudo-orthogonal sequences, is presented. Experimental results carried out by adopting a prototype system are reported. The procedure combines multiple-inputs multiple-outputs PN-sequence based impulse response measurements with an inversion procedure able to assess and localize scattering objects in the investigated area.
