使用米波超分辨雷达外场试验数据研究常用超分辨方法ＭＵＳＩＣ、最小范数法、最大似然估计法、最小无畸变响应法以及线性预测法的方向估计性能。结果表明，相比ＭＵＳＩＣ和最小范数法，线性预测法具有小的误差均值和方差，在信噪比较小的情况下，ＭＵＳＩＣ和最小范数法具有强的分辨能力。针对天线转动造成的空域谱展宽的实际情况，提出了一种相位补偿方法，使得空域谱谱峰有明显的收缩，提高了方向估计精度。
The MUSIC, the least norm method, the maximum likelihood estimation method, the minimum distortion-free response method and the direction estimation performance of the linear prediction method are studied by using the Mie-Bo super-resolution radar field data. The results show that compared with the MUSIC and the least norm method, the linear prediction method has a small error mean and variance, and MUSIC and the least norm method have strong resolving power in the case of small signal-to-noise ratio. Aiming at the actual situation of airspace spectrum broadening caused by the rotation of the antenna, a phase compensation method is proposed, which makes the airspace spectrum peak shrink significantly and improves the direction estimation accuracy.
