The new method of space resolution increasing in pulse location method was suggested by Professor Zverev is applied for space resolution improvement of ultrasonic pulse location technique. According to this method, the spectrum of the received signal is divided to the spectrum of the reference radiated signal and the complex inverse Fourier transformation is applied to the divided spectrum. This approach extends the frequency band used for analysis and highly increases the space resolution of crack location. The feasibility test was conducted with pulse ultrasonic device working with carried frequency about 3 MHz. The suggested processing was applied to the rectified signal so the frequency band of processing was restricted by 700 kHz. Even in this not optimal processing we observed the shortening of the signal reflected from a crack more than 20 times. The suggested technique was also used for spatial resolution improvement of nonlinear modulation crack imaging based on modulation of ultrasonic pulses by a crack vibration.
