Design and implementation of an antenna measurement system for the mono-pulse radar

The mono-pulse radars have been widely used in many fields such as target tracking because they have high angle measurement accuracy and good anti-jamming ability. It is important to research, develop and measure the mono-pulse radar antennas. This paper design a kind of mono-pulse antenna measurement system based on turning table, step motor controller, vector network analyzer and the Visual Basic development environment. The antenna measurement system has two channels to acquire and analyze data, then the sum and difference directional pattern of the antenna can be measured fast and accurately. Based on the theorem of the mono-pulse antenna measurement system, this paper introduces the system hardware structure and the software implementation scheme in detail. Finally, some basic practical measurements were done and the experiment measurement results indicate that the system can basically satisfy the design requirements.
