针对阵面校准中信标抖动导致相位误差超差问题,提出利用参考天线单元随动来减小相位误差的方案;同时,针对大型阵面宽带幅相修正中大盲区与高信噪比要求的矛盾,提出系留气球的解决方案。通过分析计算,证明两个解决方案在工程应用中合理可行。

[Abstract]
Aiming at the unbearable phase error caused by the beacon jitter during the calibration in antenna array, the solution is put forward to adjust the tested antenna unit together with the referenced one to reduce the phase error. Aiming at the contradiction between wide blind area and high noise-signal ratio in amplitude phase correction in wide-band systems, the consequent solution is given to fly a balloon using a wire with given length. Two solutions are proved to be feasible in engineering aplication after analysis and calculation.
