Retransmitter meter signal delay dependence on the diameter of the reflector in Fresnel zone

It has been calculated using numerical technique the phase incursion variations dependencies on plane reflector diameter for the retransmitting range meter operating in Fresnel zone. It has been determined that for the near reactive zone approach the reflector diameter variation causes fast increase of signal delay, within some places the sign of increasing changes. In the region of the Fresnel and Fraunhoffer zones boundary the dependencies become steady and speed of changing decreases with reflector moving away from the meter.
