| Abstract: | Location for a ground emitter using a satellite-mounted two dimensional interferometer is modeled and an analysis method is proposed, then the influences on the location caused by a random measurement error and system parameter errors, such as satellite attitude angle error, satellite position deviations etc., are investigated respectively. The derived result gives an account of the effect of geometrical relationship between the satellite and emitter on the location accuracy. Computer simulation results are shown and coincident with the theoretical analysis result. |
