1. Method for determining a position in space for a reflection point, using a transmitter antenna and a plurality of receiver antennas spaced apart perpendicular to a main line of sight, comprising the steps of:

  • transmitting a coherent electromagnetic wave signal towards the reflection point;

    detecting a phase difference between the transmitted signal and a reflected signal from the reflection point received in a receiver antenna;

    repeating the steps of transmitting and receiving in a plurality of frequency steps over a frequency band;

    determining a distance (r) to the reflection point by measuring variation in phase difference dependent on signal frequency; and

    identifying an angle (φ



    ) between a line of sight from the receivers to the reflection point, and the main line of sight, dependent on a delay between reception of reflected signals from the reflection point in at least two receiver antennas and a known spacing between said at least two receiver antennas.
