| Abstract: | The influence of image signal to the measurement is analyzed,which is caused by amplitude and phase imbalance of quadrature channels in multiple frequency CW radar's receiver,and a new correction method is proposed according to the principles of range and velocity measuring of the radar.The method is based on the theory of quadrature in maths,and the accuracy of the correction parameters extracted is high.The simulation results prove it. |
