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.
