Abstract：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 .
Keywords：radar networksystematic biasesCRLBestimation of target height
