Realizing the stable tracking of moving targets by the transmit-receive-coherence mode is an important symbol of the technological progress of distributed aperture coherence-synthetic radar. Firstly, the basic theory of the distributed aperture coherence-synthetic radar is briefly introduced, then, the aircraft target tracking test is analyzed from two stages of receive-coherence and transmit-receive-coherence. The test results of coherent-synthetic Signal-to-Noise Ratio(SNR) gain improvement, phase difference changes and target tracking track are given respectively. Test results show that the target tracking is stable and the SNR gain improvement is close to the theoretical value. On this basis, the test results of satellite target coherence-synthetic of two X-band large-scale phased array radars are given to realize the stable tracking of high-speed moving satellite targets in transmit-receive-coherence mode. Technical feasibility and engineering achievability of distributed aperture coherence-synthetic radar are fully verified by the test.
