摘要
在布阵平面面积一定的条件下,找到使得二维干涉仪测向精度高、解模糊概率大的几何布阵方案是很有意义的。通过理论分析得出8种不同的二维干涉仪阵型测向的CRLB,并通过计算机仿真方式分析了9元阵不同阵型的解模糊概率和各阵型不同阵元个数的解模糊概率,得出了在干涉仪面积一定条件下奇数个数阵元的圆阵是较优的布阵方式的结论。
It is meaningful to find the optimal shape for the phase interferometer to improve the direction finding accuracy and solving ambiguity probability on the condition of certain plane areas and certain element numbers.The Calmer Rao Low Bound(CRLB)of direction finding of eight different shaped 2-D interferometers are given with nine-elements.Simulations are performed to investigate the direction finding accuracy and the solving ambiguity probability of the above different shaped arrays.The theoretical analysis and simulation indicate that circular array with an odd number of elements is the best choice under certain planes areas.
