Aim To study and realize a real time video signal simulator of target′s track for monopulse radar. Methods A target′s track with playground shape was selected and the time space′s relations were given. Using the computer, the data of three channels were produced and the rang errors were made as small as possible. Based on the three channel radar′s characteristics, the synchronous problems of different channels were solved by set a sign of time. Results and conclusion The simulator can produce the target′s echo precisely. The rang error is smaller than the simulator′s step rang. The signal of three channels can be synchronized by the sign of time.
