Simulation System Of Softwar Radar Based On MATLAB

Most military radar still were used since the 1960s and 1970s the technology and equipment, and almost all of its functions from hardware to complete, has been unable to adapt to the needs of modern warfare. How to make full use of the existing radar technology to the latest achievements and development, develop a new generation of radar equipment, has become an urgent need to study and address an important issue. At the same time the actual number of weapons and equipment and the cost is limited, research and development of radar simulation software platform to become a modern radar technology of the important means to improve radar performance, and reduce hardware costs has opened up a new direction has important significance of the military and economic significance.The simulation system has the ability of implementing simulative display of moving object, producing radar signal, constructing and simulation of mixed signal's model, simulation of digital demodulation, detection of moving object, single pulse radar digital angle measuring, ranging, speed measuring and coordinate transforming. Technical person can analyze the principle and characteristic of radar system, by using the simulation system, which improves their ability of analyzing questions and researching more complex techniques. The system can be used widely in the respect of technical person training, who works with radar equipment, analyzing the radar equipments and test techniques researching. In this ways, the simulation system can offer a very good means. We have analyzed the principle theory of radar system, the basic method and application instances, based the simulation system, which make us accumulated most of the important information and knowledge in the application of reconstructing the single pulse radar equipment being used.At the same time, the paper comprehensive exposition and analysis accumulated pulse that its principle, and the method of signal detection performance improvement in allusion to radar weak signal detection technology, further, the paper raise a point of non-stationary signals in the detection method and the new long time accumulation technical problems. This study effectively raise the contents of the radar signal to noise ratio, increasing the radar range, and improve its weak signal detection ability to provide a theoretical basis, has application value.
