At present application of new technology components and have a scientific basis to the existing radar station is the right direction and in accordance with the military situation. The need for improvement and modernization radar in the Army is so great that the radar are mainly the older generation. Not only difficulty about supplies and technical equipment which sources of information theory technology radar technology from the former Soviet Union and Eastern Europe decreased significantly from other countries is very limited. Military radar receiver compared to the civil radar receivers have techniques to synthesize complex and specific characteristics. Although it is not a new problem both in theory and fabrication technology but related to the military secrets of the most developed countries as well as the commercial product should be very difficult to reach and update the .
