| With the development of computer technology, digital signal processing technology and image processing, radar information processing and video display has been widely used with computer. This method can not only reduce costs but also to be more flexible on the radar information processing, and to meet the diverse needs of the radar information display.In this paper, a display control terminals has been developed for small radar, FURUNO 1942 radar, achieving the radar control and image display. Researching and analyzing control mechanism of the radar, control terminal and each module have been designed. Radar control terminal is mainly composed of control processor and man-machine interface, and each of these two parts has been designed.This paper analyzes the radar structures, interface circuits, composition of power supply system and workflow. It also analyses the several important information of radar, as the trigger pulse, the tuning signal, PWM signal or the like. The radar control processor has been designed for hardware circuit and software program, according to the control mechanism of radar. The computer terminal man-machine interface designed in computer terminal has achieved radar control and radar states display.The control processor of FURUNO 1942 radar in this study is based on STC15F2K60S2 MCU. The computer terminal man-machine interface is based on Visual Studio 2010 C#. The system achieves control radar via computer terminal man-machine interface, and real-time monitor and process status information of radar. Radar screen size will be larger by configuring different displays, you can also configure various software to achieve configuration functions. Cheap radar transceiver and antenna are matched with high-end display control terminal, completing not only the high-performance radar display of information, but also reduce costs, improve resource utilization. In some narrow river and small vessel traffic, or some occasions where require small radar but higher performance and functionality requirements of advanced radar technology, is the simplification and miniaturized radar systems can not be met. The system has a high practical value in these special occasions. |
