Design Of Embedded Computer-based Radar Display And Control Terminals

Display and control terminal is the important component of a Radar system, which performs the man-machine interface, Radar controlling, data recording, target information displaying,etc. In this dissertation, we discuss the designing and realization of the display and control terminal of bastatic Radar testing receiver system .We choose the PC104-plus embedded single board computer as the main computer ,using its integrated multifunction and interface to achieve following task: Receiving the output signal of the GPS synchronization system and sending system parameters and control instruction to the central controller unit by serial communication mode; Recording the realtime signal processing data through the PC104-plus interface which is based on PCI bus; Displaying the text and image information of the Radar target on LCD . The function mudules of display and control terminal are performed by software. The display and control software is made up of several modules,include the Radar interface,graphical display module,serial communication module,PC104-plus interface module,database storage module. Adopting software methord to perform Radar display and control reduce the dependence of hardware,increase the flexibility of display and control terminal and Radar system.If the system parameters are needed to change or upgrade the system function,we can modify the software at the least cost. The primary work in this paper: 1.Introduce the development of bistatic Radar and the various types of display terminal. 2.Introduce the Radar system block diagram. 3.Discuss the structure, design and realization of the Radar display and control system. 4.The design and realizing of the Radar display and control software. 5.Display and control terminal,the waveform generator,the beat signal processor,the central controller and the signal processor unite test.
