针对地球曲率造成的电子战交叉定位误差问题，提出了一种基于高斯投影的迭代逼近定位算法，该方法采用高斯投影将传感器位置投影到同一坐标系，应用最小二乘法迭代逼近解算目标位置，最后将目标坐标逆投影回地理坐标系。仿真试验分析了影响定位的主要因素，证明该方法减小了曲率影响，提高了定位精度。

The iterative cross-location algorithm based on Gauss projection are proposed on the electronic warfare loca-tion error because of global curvature .The method projects the sensor position on the same reference frame by Gauss projec-tion and computes the target position by the iterative least squares ,finally reversal projects the sensor position on the geogra-phy reference .By analyzing major factors impacting the error ,the simulation results show that the method has modified the influence of global curvature and improved the precision of the location .
