1. A beam forming device comprising:

  • a transmitter arrangement comprising at least one transmit antenna that transmits radiation towards a scene,a receiver arrangement comprising at least one receive antenna that receives radiation from said scene and at least one receive unit that generates receive signals from said received radiation, wherein the total number of transmit antennas and receive antennas is at least three,a beam forming unit that performs beam forming to obtain beam formed output signals from said receive signals by use of corrected beam forming weights, anda correction unit that corrects preliminary beam forming weights in amplitude and/or phase by use of frequency-dependent final calibration coefficients representing the different amplitude and/or phase responses of the different channels between said at least one transmit antenna and said at least one receive antenna at two or more separate frequencies covered by the radiation used for illumination of the scene.
