| Data processing and display control cell is an important part of LFMCW radar system, it is mainly used to process the data obtained from the radar signal processing cell, and to display the results on the digital map intuitively, effectively and accurately. This thesis focuses on the design of LFMCW radar data processing and display control cell and the realization of the programming work. The design and realization of the software is based on ARM embedded Linux system platform.The design of LFMCW radar data processing and display control terminal cell includes algorithm studying, software architecture constructing and application software development. The OK6410board based on samsung s3c6410processor is used as hardware. The software is developed by using the host-target mode. Radar data processing algorithms includes point tracing algorithm and track processing algorithm. The development of the data processing and display control terminal application software includes:Interface program design; Digital map display program design; LFMCW radar data processing program design; LFMCW radar target information display program design; Serial communication program design. The software design is based on embedded Linux system, the Qt Creator is used as the tool to develop, and the developed software is transplanted to the OK6410board. On the basis, the data processing and display control terminal is debugged and tested on the radar system. The developed LFMCW radar data processing and display control terminal has good portability, reliability and stability; it conforms to the requirements of the system. |
