Abstract  The radar system simulation is the product of the combination of digital simulation technology and radar technology. Compared with the field test, the radar system simulation economy, flexibility, repeatability, inheritable, etc., and thus become a necessary prerequisite for development and production of modern radar.Angle measurement is the determination of the pitch angle and azimuth of the target, it is the goal orientation, an important part of the precision-guided. Widely used because of its rapidity, accuracy and poor single pulse goniometer. Angle measurement using the idea of combining the theory of signal processing and MATLAB simulation software simulation, not only to provide a convenient computing, but also to get good accuracy.

  The paper first discusses the basic principles of the radar system. At home and abroad in recent years, single-pulse radar system implementations simple overview. And introduced several common angle measurement method, the form of the realization of the single-pulse system.

Keywords: single-pulse radar, echo signal, sum and difference beam
