Abstract: Electrical signal source is often used to excite swingscanning earth sensor during the ground test of satellite.In order to reveal sensor’s actual characteristics and reduce the electrical source error, measurement model and scanning equation of sensor are deduced in this paper.The electrical source error is analyzed theoretically, and then an improved method is introduced. This method has clear concept and little computational requirement. Test results demonstrate that the high precision of sensor electrical source can be achieved with this algorithm.
