Investigation Of Improving 154A Interferometer's Up Channel

In this paper, the principle of out-trajectory measurement radar of 154A interferometer is presented, the theory of the up channel is emphasized, and the main problem existing in the up channel is analyzed.There are many faults existing in the 154A interferometer, for instance, the random error in the main velocity measure channel will extend the limit between times. The paper introduce the muck work for solving the main problem by doing much experiment and analyzing .In this course, according to the practice of shooting range and the scarce outlay, we find the cause of the problem, improve the quality of the up channel signals, solve the problem effectively, and improve the accuracy of the system.The paper presents the realization for the linkage for weak signal system, and finds the new method for the linkage of the powerful radar. Therefore, we can cut down the radiation influence coming from the radar, improve the work environment, low the cost, and improve the credibility of the radar.
