(EN) The invention relates to a method for measuring the elevation angle (Phi E) and/or azimuth angle (Phi A) using an antenna arrangement, wherein the antenna arrangement comprises at least two transmission antennas (Tx), which are at a horizontal and a vertical distance (dTx,dTy) from one another, at least four reception antennas (Rx), which are at a horizontal distance (dR) from one another, and a monolithic microwave circuit, wherein identical transmission signals consisting of successive, linear-frequency-modulated ramps are transmitted via the transmission antenna (Tx) of the antenna arrangement using time division multiplexing, wherein the time division multiplexing is achieved by alternately damping the signals emitted by the transmission antennas (Tx),wherein echos of the transmissionsignals are received by the reception antennas (Rx) and are downconverted to a baseband and sampled, wherein the downconverted and sampled echos are transformed into a 2D image domain by means of an FFT, wherein phase differences (Delta Phi1, Delta Phi 2) are determined from the image data, and wherein for compensation of a systematic error present owing to the lack of separation of the two transmission signals, after the measurement of the phase differences (Delta Phi 1, Delta Phi 2) or after the measurement of the phase differences (Delta Phi 1, Delta Phi 2) and the calculation of an azimuthangle (I) or elevation angle (II) which is erroneous on account of the lack of separation of the transmission signals, from the measured phase differences, an error-compensated elevation angle and/oran error-compensated azimuth angle is determined by means of a compensation.
