  • A new method was developed to estimate the radar system phase bias and calibrate the radar system. Using the data collected by this radar, the phase differences of the meteor echo between each receiver pairs are estimated, by taking account of the receiver pairs geometries the linear equation matrix is formed, the phase bias between each receiver pairs in the least-squares sense is solved, and finally the location of meteor echoes after calibration is found. Compared with the conventional method, this method can use the history data to find the system phase bias, without the need for additional hardware. It can routinely use for off-line to correct data collected using the bias estimated before. The data of Wuhan Meteor Radar (WHMR) between April 2004 to June 2004 is used as an example, the bias of the radar system is estimated and the data is used after calibration to calculate the location of the meteor echoes. The data calibrated using this method show a more consistent height distribution in terms of number of echoes with the same meridian.
