Abstract :
A well suited approach devoted to weak non line of sight (NLOS) signal measurement is described. By using the principle of nulling interferometry either in the spatial domain or in the spectral domain, one can achieve line of sight (LOS) dimming, and then NLOS emphasis. This operation, tested in the millimeter band, is highly requested when phase carrier measurement is carried out such as for accurate indoor positioning
