摘　　要：针对传统的抗干扰双站测向交叉定位方法存在的基线及其延长线附近无法实现对目标准确定位的问题,利用预警机装备的优点,提出了一种基于预警机支援的空地协同目标定位方法。该方法使用预警机提供的目标高度信息,以及地面雷达提供的角度信息,在数据处理中心进行目标距离的解算,克服了如上所述的双站测向交叉定位的缺点。分析了该方法的解算精度,经过仿真证明了该方法的可行性。Bistation bearing-only cross locating is a common and widely-used locating method in radar network. The locating error increases rapidly near baseline and its elongation line, thus it is difficult to implement accurate target locating. To solve the problem, an air-ground cooperative target location method is proposed based on the support of AWACS. By using the target altitude information supplied by AWACS and target angle information supplied by ground radar, the distance to the target can be calculated out in data processing center. The drawback of the bistation bearing-only cross locating is overcome. The precision of the algorithm is analyzed. Simulation showed the feasibility of the method.
