Abstract
The study of phased array radar （ P A R ） pulse amplitude sequence characteristics is the key tounderstand the radar5 s working state and its beam 5 s scanning manner. According to the principle of antennapattern formation and the searching and tracking modes of beams, this paper analyzes the characteristics anddifferences of pulse amplitude sequence when the radar beams work in searching and tracking modesrespectively. Then an optimal sorting model of pulse amplitude sequence is established based on least-squaresand curve-fitting methods. This method is helpful for acquiring the current working state of the radar andrecognizing its instantaneous beam pointing by sorting the pulse amplitude sequence without the necessity toestimate the antenna pattern.
