A Kind Of Individual Target Reconnaissance Design Positioning Terminal

Target positioning plays an important role in the modern war. Nowadays, with the development of science and technology, target positioning has been greatly changed.The BDS can be used officially in China and the surrounding area. It provides the accurate location information for the user,and provides a good technical support.This paper presents a measuring of the target positioning by local coordinate,target distance and target angle.The BDS module CC50-BG can provide measurement of longitude, latitude and altitude of local. The magnetoresistive sensor and accelerometer and angular correlation circuit measure the azimuth angle and pitching angle between local and target point. Then the control circuit through the interface circuit of RS-232and I/O, will be fixed on the concentric laser distance measuring equipment,and measure the distance.Finally, the main control module will deal with the three parameters and calculate the longitude,the latitude and the altitude, and display on the LCD. The users can operate the terminal by the keyboard to achieve the goal of the target positioning, data storage, data query, delete data, data transmission and other related functions.In this paper, the main contents are as follows:First,this paper introduced the concept of the embedded system and the development process of the embedded system, built the overall framework design.Then this paper introduced the principle of the target positioning, listed several methods for target positioning, and selected the most suitable method:measuring the local longitude, latitude, altitude, and the distance between local and the target point, the angle between local and the target point.Afterwards, this paper introduced the design of the hardware circuit, the principle of each module, and the hardware circuit.Finally, this paper introduced the design of the software, the flow chart of software design, and the test results and data analysis.
