Low angle tracking with symmetric beam pattern monopulse based on uniform circular array
In this paper,the problem of low angle tracking is studied on the viewpoint of improving monopulse.We applied the traditional symmetrical monopulse ratio method to the uniform circular array.By dividing the circular antenna array into two equivalent sub arrays,a symmetrical monopulse ratio is formed,which could overcome the difficulty of angle measurement caused by multipath and meet the requirements of low angle tracking.The monopulse response curve and the precision of angle measurement are analysed by simulative experiments.Negative factors including thermal noise,asymmetrical multipath,signal-to-noise ratio(SNR)and reflection coefficient are discussed intensively with respect to the accuracy of our method.
