摘要
为进一步提高传统相位干涉仪测角精度,提出一种利用所有基线信息的新测角方法。在给出该测角方法的基础上,分析了该方法的测角精度。理论分析表明该方法测角精度优于传统方法,可适用于一维和二维线阵,且不改变现有阵列的布阵形式,算法计算量小。仿真结果验证了理论分析的正确性,且在低信噪比情况下,该方法测角性能提高更加明显。
In order to further improve the angle accuracy of the traditional phase interferometer,a novel measuring angle method using all baseline information is introduced.The angle accuracy of the method is analyzed theoretically.The analysis shows that the angle accuracy of the method without extra computational loads is superior to that of the traditional method.The proposed method is suitable for 1 Dand 2 Dlinear array without changing the array form of the existing array.Simulation results verify the correctness of the propose method,and the accuracy of the method is more obvious in the case of low SNR.
