摘　　要：提出了通过双机雷达对同一目标的距离向信息进行高精度协同定位算法。针对远距离目标,利用雷达距离向精度高的特点,基于双机雷达的距离向实现目标的高精度定位。给出了双机雷达协同定位的原理,仿真分析了目标距离、雷达组网布局、目标速度、协同定位时延等不同的因素对协同定位精度的影响,分析出最佳雷达组网布局,提出协同定位时延要求,具有重要的工程应用意义。A high precision co-location algorithm for the same target’s range-direction information by two radars is proposed in this paper. For long distance targets,the high precision positioning of the target is realized based on the range information of the two radars by the high accuracy of the range direction of the radar. The principle of co-location of two radars is given,and the influence of different factors on the accuracy of co-location algorithm,such as target distance,radar network layout,target speed and co-location delay,is simulated and analyzed. The optimal radar network layout is analyzed and the requirements of co-location delay are put forward,which has important engineering application significance.
