【Abstract】 With the use of measuring datum of common targets,a sensor precision evaluation method for data fusion system was put forward to meet the conditions under which the true value of targets’states is unknown.The principles and data process procedure for sensor precision evaluation was described in detail.The ability of parameter evaluation of sensor precision was analyzed and the computer simulations were made.All the results showed that the proposed evaluation method is feasible,the evaluated results are unbiased,and the precision of the evaluated results can be improved by accumulating more measuring datum of the common targets from sensors.更多还原
