Abstract

The invention provides an angle measurement method for a secondary surveillance radar. The method comprises the step that a direction of an incoming wave is determined by utilizing a two-dimensional phase interferometer, conducting two-dimensional angle measurement computation and utilizing a phase difference formed by a radio wave on a base line. With the adoption of the method, surveillance and control of a secondary surveillance radar system to a target can be achieved; the method is simple to achieve, and has a certain application value to a special application occasion of the secondary surveillance radar; and the problem that one-dimensional angle measurement is inaccurate is solved.

Description

technical field [0001] The invention relates to a method for realizing azimuth angle measurement of a secondary surveillance radar, which belongs to the field of radar radios. Background technique [0002] Secondary Surveillance Radar (SSR) is mainly used for real-time monitoring of the flight situation of military and civil aircraft, and provides radar data for controllers to conduct air traffic control on military and civil aircraft. The secondary surveillance radar system measures the distance of the target aircraft based on the time difference of arrival (TOA) principle. The height of the target is obtained indirectly from the data transmitted by the target aircraft, and the azimuth of the target is obtained by measuring the target within the scanning beam. position is obtained. [0003] In engineering applications, there are many ways to measure the azimuth angle of the target in the SSR system, such as: sliding window angle measurement, phase sum difference monopulse ...
