Annotation: Two methods of the multichannel processing, which allow to enhance the determination accuracy of the signal delay, are considered. The time delay of a signal has been found with the use of threshold method at the level of detection threshold. The experimental results have been processed, and the statistical characteristics of the estimates of radiofrequency pulse signal delay have been obtained.
