Abstract :
The bias of the radar measured coordinate value of a star compared to the theoretical coordinate value, accurately calculated from astronomical knowledge, can be used to find out those mechanical factors affecting the accuracy of the radar measurement in azimuth and elevation. Thus the raw target coordinate values obtained from a radar system could be calibrated. A high accuracy of estimated error coefficients can be obtained by using least squares methods and calculating the apparent position coordinates in a rectangular coordinate system. Both the theory and software implementation of star calibration for instrumentation radar are described in this paper
