Abstract：In order to promote each aircraft recall capability and efficiency，lower the aircraft recall equipment scale，this text proposed a kind of GOLD array that makes according to the two - phase code false random code repeatedly two radars of differences of system，have the high definition of warship machine telecommunication capability to measure to lead radar to carry out a method. From the system of select design，GOLD array code frequency the correction and telecommunication information solve calculate accuracy，imitate true test etc. introduced how to provide system vs the aircraft nicety measure at the same time，realize and machine carry an of equipment the information transmission of the high speed rate，high accuracy. Testing enunciation through engineering realize and test，the method not only assured the measurement accuracy of radar，but also carried out warship machine top speed telecommunication and had importance reference meaning to each kind of consortium object recall.
