In order to enhance the coordination of different positions of monopulse measuring radar in the field of aerospace measurement and control, to improve the working condition of radar transmitter operator, this article puts forward a transmitter video monitor system based on template matching. Firstly, the feasibility of the state inspection using template matching method is discussed, then the digital image of the working state captured from the transmitter is divided, the identification of the working condition by template matching is employed and finally the working state of the transmitter is shown according to the matching result. Through designing the prototype of monitoring system, the feasibility of the algorithm is verified and the light of the control module in the transmitter is identified.
