一种基于波束重置提高测角精度的方法OA

Aiming at the problem that the modulation of the echo signal by beam when radar rotates leads to the decline of accuracy in amplitude comparison angle measurement of multi-pulse accumulation radar,this paper first analyzes the mechanism of the deterioration of angle measurement accuracy,then puts forward a method to improve the angle measurement accuracy base on beam reset,and finally carries out simulation analysis and exper-imental verification.The simulation and test results show that this method is feasible and effective,and that when the number of accumulated pulses is larger,the proposed method has higher measurement accuracy and wider ap-plication range,compared with the traditional method.
