High quality satellite, fibre and mobile communications are an essential part of modern life and vital to European Industry, with increasing demand for telecommunications growing at 40 %. This work develops algorithmic methods allowing traceability in both the measurement and the arithmetic exploitation of the radiated field of antenna. This development has been achieved from electromagnetics simulation with the software CST microwave studio and the Matlab calculator for the algorithmic approaches. Microwave holography allows calculating the field distribution of antenna for different distances between the antenna and the receiver from an initial measurement. The interpolation method allows obtaining a field distribution of antenna with a matrix mesh more thin from a measurement with a matrix mesh more large. In this work, we show the uncertainties propagation using Monte Carlo method. This study allows showing the limits of using algorithms and the parameters which are at the origin of these limits.
