Description

technical field [0001] The invention relates to the field of air traffic management, in particular to a verification method and a verification system for an angle measurement function of a single pulse angle measurement device. Background technique [0002] Secondary radar equipment plays an important role in air traffic control. It can provide control staff with higher-precision data than radar, and can also provide control staff with identification information (aircraft code). When an aircraft fails, communication Information that can provide danger warnings in the event of system failure or hijacking. Therefore, it is particularly important to improve the angle measurement accuracy and ranging accuracy of the secondary radar. [0003] When measuring the angle of secondary radar, the influence of various factors will produce angle measurement errors. According to the type of error, it can be divided into systematic error and random error. System error can be eliminated or...
