摘　　要：探讨了将目标在载机坐标系中的坐标变换到地面站直角坐标系中,实现目标定位的方法,并对其进行了误差分析。进而根据预警机机载雷达和地面防空雷达的优点,提出了利用预警机测距信息和地面雷达站测角信息,实现交叉定位的空地协同定位新方法,并对该方法进行了精度分析。通过仿真分析了2种方法的优缺点,给出了2种方法的适用范围。A targets location method turning the location of the targets from the aircraf coordinates to the ground station cartesian coordinates was discussed, and the error of the method was analysed. Considering the advantage of AWACS radar and ground air defence radar, a new biracial sensing cross location method using the ranging information from AWACS and the angle measurement information from ground station radar was proposed, and accuracy of the method was analysed. The advantages of the two methods were analysis by simulation, and application scope of them was proposed.
