Aiming at the problem of radar sensor registration on a mobile platform. this study uses multiple radars to estimate the biases of the radar under the earth-centred earth-fixed coordinate system. which provides more accurate information for data fusion. Compared to the maximum likelihood registration (MLR) algorithm. https://www.roneverhart.com/Prudence-Sacred-Armor-Eth-Bugged-170-ED-25-34-Res-West-Non-Ladder/
