The Study Of The Catching And Trace About The Weak Signal Based DSP

Along with the development of the science technique, the system that automatically recognition target (ART) has become an extremely important part for the present and the future weapon system in the military field.Among them weak signal target real-time examination, identify, catching and trace that has become the main study direction in the domestic and international range for photoelectrical measure equipments. In this theses, a kind of real-time image measurement system based DSP that is used to process weak signal is introduced. A high speed digital signal processor TMS320C6202 is a kernel device in this system, combined with FPGA. This system not only meets the real time request but also has the function to automatically identify and measure target.This theses mostly studied a series of arithmetic of image pretreatment, image segmentation and image matching for image data, referring to advance image processing technique overseas at present. Regarding the real-time image measurement system as the tool for debugging, it finds appropriate arithmetics to process real-time image and applies them to actual hardware equipment, and make the system much accurate and much real time. Though that it is better to the question that target is probed in 4% correlation based on the real time image processing.
