针对雷达普遍存在距离和角度量测系统误差工程实际情况，以及现有两坐标雷达目标高度可观测分析和估计技术缺乏对雷达系统误差考虑不足之处，论文利用 Fisher 信息矩阵，通过求解 CRLB 下限，对系统误差下的两坐标雷达目标高度可观测分析问题进行了深入研究，并通过数值仿真，对系统误差、雷达配置对目标高度可观测的影响以及目标高度估计精度等问题进行了分析，给出了有用结论，为后续系统误差情况下目标高度估计提供了指导。

According to the actual condition of the 2D radar measurements about range and azimuth general contain sys‐tematic biases ,and aiming to the deficiencies of the existing observability analysis method and estimation technology which don't take radar systematic biases into account ,the paper deeply researches the observability analysis problem about 2D radar height estimation when considering systematic biases through solving CRLB by Fisher information matrix .The problems that the influence of systematic biases and radar disposition on the target height observability and the estimation accuracy of target height are analyzed by simulation .The useful conclusions are drawn ,which can offer guidance to the height estimation in conditions of systematic biases .
