A method of angle error extraction for monopulse radar with 3-subarray variable polarization antenna

To improve the ability of radar´s anti-jamming and target recognition, polarization technology is applied to monopulse angle measurement. 3-subarray millimetre wave variable polarization array antenna is also proposed and discussed in this paper. A novel method of angle error extraction in horizontal and vertical direction is given by analyzing polarization synthesis and electric field of the antenna, meanwhile, the difference between the new method and traditional one is discussed. Finally, according to the new method, simulation results of angle error extraction are presented.
