Modeling and angle measuring simulation of radar antenna sum-difference pulse beam

Mono-pulse radar is widely used for its short measuring time, high angle measurement accuracy and powerful anti-jamming performance. In this paper, sum-difference pulse beam of radar antenna is modeled by the MATLAB software. Then the echo signal angle measurement is simulated by processing the echo signal with the theory of antenna pattern, which can not only provides a convenient computing, but also gets a good accuracy.
